+# A2A Client Sample
+Show how to create an A2A Client with a command line interface which invokes agents using the A2A protocol.
+
+## Run the Sample
+
+To run the sample, follow these steps:
+
+1. Run the A2A client:
+    ```bash
+    cd A2AClient
+    dotnet run
+    ```  
+2. Enter your request e.g. "Show me all invoices for Contoso?"
+
+## Set Secrets with Secret Manager
+
+The agent urls are provided as a ` ` delimited list of strings
+
+```text
+cd dotnet/samples/Demos/A2AClientServer/A2AClient
+
+dotnet user-secrets set "A2AClient:ModelId" "..."
+dotnet user-secrets set "A2AClient":ApiKey" "..."
+dotnet user-secrets set "A2AClient:AgentUrls" "http://localhost:5000/policy;http://localhost:5000/invoice;http://localhost:5000/logistics"
+```

+# A2A Client and Server samples
+
+> **Warning**
+> The [A2A protocol](https://google.github.io/A2A/) is still under development and changing fast.
+> We will try to keep these samples updated as the protocol evolves.
+
+These samples are built with [SharpA2A.Core](https://www.nuget.org/packages/SharpA2A.Core) and demonstrate:
+
+1. Creating an A2A Server which makes an agent available via the A2A protocol.
+2. Creating an A2A Client with a command line interface which invokes agents using the A2A protocol.
+
+The demonstration has two components:
+
+1. `A2AServer` - You will run three instances of the server to correspond to three A2A servers each providing a single Agent i.e., the Invoice, Policy and Logistics agents.
+2. `A2AClient` - This represents a client application which will connect to the remote A2A servers using the A2A protocol so that it can use those agents when answering questions you will ask.
+
+<img src="./demo-architecture.png" alt="Demo Architecture"/>
+
+## Configuring Secrets or Environment Variables
+
+The samples can be configured to use chat completion agents or Azure AI agents.
+
+### Configuring for use with Chat Completion Agents
+
+Provide your OpenAI API key via .Net secrets
+
+```bash
+dotnet user-secrets set "A2AClient:ApiKey" "..."
+```
+
+Optionally if you want to use chat completion agents in the server then set the OpenAI key for the server to use.
+
+```bash
+dotnet user-secrets set "A2AServer:ApiKey" "..."
+```
+
+Use the following commands to run each A2A server:
+
+```bash
+cd A2AServer
+dotnet run --urls "http://localhost:5000;https://localhost:5010" --agentType "invoice"
+```
+
+```bash
+cd A2AServer
+dotnet run --urls "http://localhost:5001;https://localhost:5011" --agentType "policy"
+```
+
+```bash
+cd A2AServer
+dotnet run --urls "http://localhost:5002;https://localhost:5012" --agentType "logistics"
+```
+
+### Configuring for use with Azure AI Agents
+
+You must create the agents in an Azure AI Foundry project and then provide the project endpoint and agents ids. The instructions for each agent are as follows:
+
+- Invoice Agent
+    ```
+    You specialize in handling queries related to invoices.
+    ```
+- Policy Agent
+    ```
+    You specialize in handling queries related to policies and customer communications.
+
+    Always reply with exactly this text:
+
+    Policy: Short Shipment Dispute Handling Policy V2.1
+
+    Summary: "For short shipments reported by customers, first verify internal shipment records
+    (SAP) and physical logistics scan data (BigQuery). If discrepancy is confirmed and logistics data
+    shows fewer items packed than invoiced, issue a credit for the missing items. Document the
+    resolution in SAP CRM and notify the customer via email within 2 business days, referencing the
+    original invoice and the credit memo number. Use the 'Formal Credit Notification' email
+    template."
+    ```
+- Logistics Agent
+    ```
+    You specialize in handling queries related to logistics.
+
+    Always reply with exactly:
+
+        Shipment number: SHPMT-SAP-001
+        Item: TSHIRT-RED-L
+        Quantity: 900"
+    ```
+
+```bash
+dotnet user-secrets set "A2AServer:Endpoint" "..."
+```
+
+Use the following commands to run each A2A server
+
+```bash
+cd A2AServer
+dotnet run --urls "http://localhost:5000;https://localhost:5010" --agentId "<Invoice Agent Id>" --agentType "invoice"
+```
+
+```bash
+cd A2AServer
+dotnet run --urls "http://localhost:5001;https://localhost:5011" --agentId "<Policy Agent Id>" --agentType "policy"
+```
+
+```bash
+cd A2AServer
+dotnet run --urls "http://localhost:5002;https://localhost:5012" --agentId "<Logistics Agent Id>" --agentType "logistics"
+```
+
+### Testing the Agents using the Rest Client
+
+This sample contains a [.http file](https://learn.microsoft.com/aspnet/core/test/http-files?view=aspnetcore-9.0) which can be used to test the agent.
+
+1. In Visual Studio open [./A2AServer/A2AServer.http](./A2AServer/A2AServer.http)
+1. There are two sent requests for each agent, e.g., for the invoice agent:
+    1. Query agent card for the invoice agent
+        `GET {{hostInvoice}}/.well-known/agent.json`
+    1. Send a message to the invoice agent
+        ```
+        POST {{hostInvoice}}
+        Content-Type: application/json
+
+        {
+            "id": "1",
+            "jsonrpc": "2.0",
+            "method": "message/send",
+            "params": {
+                "id": "12345",
+                "message": {
+                    "role": "user",
+                    "messageId": "msg_1",
+                    "parts": [
+                        {
+                            "kind": "text",
+                            "text": "Show me all invoices for Contoso?"
+                        }
+                    ]
+                }
+            }
+        }
+        ```
+
+Sample output from the request to display the agent card:
+
+<img src="./rest-client-agent-card.png" alt="Agent Card"/>
+
+Sample output from the request to send a message to the agent via A2A protocol:
+
+<img src="./rest-client-send-message.png" alt="Send Message"/>
+
+### Testing the Agents using the A2A Inspector
+
+The A2A Inspector is a web-based tool designed to help developers inspect, debug, and validate servers that implement the Google A2A (Agent-to-Agent) protocol. It provides a user-friendly interface to interact with an A2A agent, view communication, and ensure specification compliance.
+
+For more information go [here](https://github.com/a2aproject/a2a-inspector).
+
+Running the [inspector with Docker](https://github.com/a2aproject/a2a-inspector?tab=readme-ov-file#option-two-run-with-docker) is the easiest way to get started.
+
+1. Navigate to the A2A Inspector in your browser: [http://127.0.0.1:8080/](http://127.0.0.1:8080/)
+1. Enter the URL of the Agent you are running e.g., [http://host.docker.internal:5000](http://host.docker.internal:5000)
+1. Connect to the agent and the agent card will be displayed and validated.
+1. Type a message and send it to the agent using A2A protocol.
+    1. The response will be validated automatically and then displayed in the UI.
+    1. You can select the response to view the raw json.
+
+Agent card after connecting to an agent using the A2A protocol:

+
+Raw JSON response from an A2A agent:
+
+<img src="./a2a-inspector-raw-json-response.png" alt="Response Raw JSON"/>
+
+### Configuring Agents for the A2A Client
+
+The A2A client will connect to remote agents using the A2A protocol.
+
+By default the client will connect to the invoice, policy and logistics agents provided by the sample A2A Server.
+
+These are available at the following URL's:
+
+- Invoice Agent: http://localhost:5000/ 
+- Policy Agent: http://localhost:5001/ 
+- Logistics Agent: http://localhost:5002/
+
+If you want to change which agents are using then set the agents url as a space delimited string as follows:
+
+```bash
+dotnet user-secrets set "A2AClient:AgentUrls" "http://localhost:5000/;http://localhost:5001/;http://localhost:5002/"
+```
+
+## Run the Sample
+
+To run the sample, follow these steps:
+
+1. Run the A2A server's using the commands shown earlier
+2. Run the A2A client:
+    ```bash
+    cd A2AClient
+    dotnet run
+    ```  
+3. Enter your request e.g. "Customer is disputing transaction TICKET-XYZ987 as they claim the received fewer t-shirts than ordered."
+4. The host client agent will call the remote agents, these calls will be displayed as console output. The final answer will use information from the remote agents. The sample below includes all three agents but in your case you may only see the policy and invoice agent.
+
+Sample output from the A2A client:
+
+```
+A2AClient> dotnet run
+info: A2AClient[0]
+      Initializing Semantic Kernel agent with model: gpt-4o-mini
+
+User (:q or quit to exit): Customer is disputing transaction TICKET-XYZ987 as they claim the received fewer t-shirts than ordered.
+
+Calling Agent InvoiceAgent with arguments:
+      query: TICKET-XYZ987
+      instructions: Investigate the transaction details for TICKET-XYZ987 and verify the number of t-shirts ordered versus the number received.
+
+Response from Agent InvoiceAgent:
+    The invoice associated with the transaction ID TICKET-XYZ987 is for the company Contoso. It was issued on June 18, 2025. The products in the invoice include 150 T-Shirts priced at $10.00 each, 200 Hats priced at $15.00 each, and 300 Glasses priced at $5.00 each. If you need more details or a copy of the invoice, please let me know!
+
+Calling Agent LogisticsAgent with arguments:
+      query: TICKET-XYZ987
+      instructions: Check the shipping details for TICKET-XYZ987, specifically the quantity of t-shirts dispatched to confirm if fewer t-shirts were sent.
+
+Response from Agent LogisticsAgent:
+    Shipment number: SHPMT-SAP-001
+    Item: TSHIRT-RED-L
+    Quantity: 900
+
+Calling Agent PolicyAgent with arguments:
+      query: TICKET-XYZ987
+      instructions: Review the policy regarding disputes and claims related to shipment discrepancies, especially concerning t-shirts.
+
+Response from Agent PolicyAgent:
+    Policy: Short Shipment Dispute Handling Policy V2.1
+
+    Summary: "For short shipments reported by customers, first verify internal shipment records
+    (SAP) and physical logistics scan data (BigQuery). If discrepancy is confirmed and logistics data
+    shows fewer items packed than invoiced, issue a credit for the missing items. Document the
+    resolution in SAP CRM and notify the customer via email within 2 business days, referencing the
+    original invoice and the credit memo number. Use the 'Formal Credit Notification' email
+    template."
+
+Agent: Here's the investigation result for transaction TICKET-XYZ987:
+
+1. **Invoice Details**: The invoice for transaction TICKET-XYZ987 indicates that 150 t-shirts were ordered.
+
+2. **Shipment Details**: The logistics records show that a total of 900 t-shirts were dispatched under the shipment number SHPMT-SAP-001.
+
+There seems to be a significant discrepancy between the number of t-shirts ordered and the number shipped. According to the Short Shipment Dispute Handling Policy, the next steps are as follows:
+
+1. **Confirm Discrepancy**: Since the logistics data confirms that 900 t-shirts were packed, it is necessary to check if this aligns with the customer's claim.
+
+2. **Issue Credit**: If the customer is indeed correct and fewer items were actually received compared to what was invoiced, you would need to issue a credit for the missing items.
+
+3. **Document Resolution**: Ensure to document the resolution in SAP CRM.
+
+4. **Notify the Customer**: Notify the customer via email within 2 business days, using the 'Formal Credit Notification' email template, and reference both the original invoice and the credit memo number.
+
+Please let me know if you would like to proceed with any specific action!

+# AI Model Router
+
+This sample demonstrates how to implement an AI Model Router using Semantic Kernel connectors to direct requests to various AI models based on user input. As part of this example we integrate LMStudio, Ollama, and OpenAI, utilizing the OpenAI Connector for LMStudio and Ollama due to their compatibility with the OpenAI API.
+
+> [!IMPORTANT]
+> You can modify to use any other combination of connector or OpenAI compatible API model provider.
+
+## Semantic Kernel Features Used
+
+- [Chat Completion Service](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/IChatCompletionService.cs) - Using the Chat Completion Service [OpenAI Connector implementation](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/Connectors/Connectors.OpenAI/Services/OpenAIChatCompletionService.cs) to generate responses from the LLM.
+- [Filters](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/IChatCompletionService.cs), using to capture selected service and log in the console.
+
+## Prerequisites
+
+- [.NET 10](https://dotnet.microsoft.com/download/dotnet/10.0).
+
+## Configuring the sample
+
+The sample can be configured by using the command line with .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests.
+
+### Using .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets)
+
+```powershell
+dotnet user-secrets set "OpenAI:ApiKey" ".. api key .."
+dotnet user-secrets set "OpenAI:ChatModelId" ".. chat completion model .." (default: gpt-4o)
+dotnet user-secrets set "AzureOpenAI:Endpoint" ".. endpoint .."
+dotnet user-secrets set "AzureOpenAI:ChatDeploymentName" ".. chat deployment name .." (default: gpt-4o)
+dotnet user-secrets set "AzureOpenAI:ApiKey" ".. api key .." (default: Authenticate with Azure CLI credential)
+dotnet user-secrets set "AzureAIInference:ApiKey" ".. api key .."
+dotnet user-secrets set "AzureAIInference:Endpoint" ".. endpoint .."
+dotnet user-secrets set "AzureAIInference:ChatModelId" ".. chat completion model .."
+dotnet user-secrets set "LMStudio:Endpoint" ".. endpoint .." (default: http://localhost:1234)
+dotnet user-secrets set "Ollama:ModelId" ".. model id .."
+dotnet user-secrets set "Ollama:Endpoint" ".. endpoint .." (default: http://localhost:11434)
+dotnet user-secrets set "Onnx:ModelId" ".. model id .."
+dotnet user-secrets set "Onnx:ModelPath" ".. model folder path .."
+```
+
+## Running the sample
+
+After configuring the sample, to build and run the console application just hit `F5`.
+
+To build and run the console application from the terminal use the following commands:
+
+```powershell
+dotnet build
+dotnet run
+```
+
+### Example of a conversation
+
+> **User** > OpenAI, what is Jupiter? Keep it simple.
+
+> **Assistant** > Sure! Jupiter is the largest planet in our solar system. It's a gas giant, mostly made of hydrogen and helium, and it has a lot of storms, including the famous Great Red Spot. Jupiter also has at least 79 moons.
+
+> **User** > Ollama, what is Jupiter? Keep it simple.
+
+> **Assistant** > Jupiter is a giant planet in our solar system known for being the largest and most massive, famous for its spectacled clouds and dozens of moons including Ganymede which is bigger than Earth!
+
+> **User** > LMStudio, what is Jupiter? Keep it simple.
+
+> **Assistant** > Jupiter is the fifth planet from the Sun in our Solar System and one of its gas giants alongside Saturn, Uranus, and Neptune. It's famous for having a massive storm called the Great Red Spot that has been raging for hundreds of years.

+# Agent hosting
+
+This folder contains a set of Aspire projects that demonstrate how to host a chat completion agent on Azure as a containerized service.
+
+## Getting started
+
+### Initialize the project
+
+1. Open a terminal and navigate to the `AgentFrameworkWithAspire` directory.
+2. Initialize the project by running the `azd init` command. **azd** will inspect the directory structure and determine the type of the app.
+3. Select the `Use code in the current directory` option when **azd** prompts you with two app initialization options.
+4. Select the `Confirm and continue initializing my app` option to confirm that **azd** found the correct `ChatWithAgent.AppHost` project.
+5. Enter an environment name which is used to name provisioned resources.
+
+### Deploy and provision the agent
+
+1. Authenticate with Azure by running the `az login` command.
+2. Provision all required resources and deploy the app to Azure by running the `azd up` command.
+3. Select the subscription and location of the resources where the app will be deployed when prompted.
+4. Provide required connection strings when prompted. More information on connection strings can be found in the [Connection strings](#connection-strings) section.
+5. Copy the app endpoint URL from the output of the `azd up` command and paste it into a browser to see the app dashboard.
+6. Click on the web frontend app link on the dashboard to navigate to the app.
+
+Now you have the agent up and running on Azure. You can interact with the agent by typing messages in the chat window.
+ 
+### Next steps
+
+- [Enable RAG](#enable-rag)
+
+### Additional information
+- [Agent configuration](#agent-configuration)
+- [Running agent locally](#running-agent-locally)
+- [Clean up the resources](#clean-up-the-resources)
+- [Deploy a .NET Aspire project(in-depth guide)](https://learn.microsoft.com/en-us/dotnet/aspire/deployment/azure/aca-deployment-azd-in-depth?tabs=windows)
+
+## Agent configuration
+
+The agent is defined by the `AgentDefinition.yaml` and `AgentWithRagDefinition.yaml` handlebar prompt templates, which are located in the `Resources` folder 
+of the `ChatWithAgent.ApiService` project. The `AgentDefinition.yaml` template is used for a basic, non-RAG experience when RAG is not enabled.
+Conversely, the `AgentWithRagDefinition.yaml` template is used when RAG is enabled.
+   
+To configure the agent, open one of the templates and modify the properties as needed. The following properties are available:
+
+```yaml
+name: <The name of the agent>
+template: <The agent instructions>
+template_format: handlebars
+description: <The agent description>
+execution_settings:
+  default:
+    temperature: 0
+```
+
+- `name`: This property defines the name of the agent. For example, `SupportBot` could be a name for an agent that provides customer support.
+- `template`: This property gives specific instructions on how the agent should interact with users. An example could be, `Greet the user, ask how you can help, and provide solutions based on their questions.` This guides the agent on how to initiate conversations and respond to user inquiries.
+- `description`: This property provides a brief description of the agent's role or purpose. For instance, `This bot assists users with support inquiries.` describes that the bot is intended to help users with their support-related questions.
+- `temperature`: This property controls the randomness of the agent's responses. A higher temperature value results in more creative responses, while a lower value results in more predictable responses.
+
+Other, model specific execution settings can be added to the `execution_settings` property along the `temperature` property to further customize the agent's behavior.
+For example, the `stop_sequence` property can be added to specify a sequence of tokens that the agent should stop generating at.
+List of available execution settings for a particular model can be found in the list of derived classes of the [PromptExecutionSettings](https://learn.microsoft.com/en-us/dotnet/api/microsoft.semantickernel.promptexecutionsettings?view=semantic-kernel-dotnet) class.
+
+### Chat completion model configuration
+
+The supported chat completion model configurations are located in the `AIServices` section of the `appsettings.json` file of the `ChatWithAgent.AppHost` project:
+
+```json
+{
+  "AIServices": {
+    "AzureOpenAIChat": {
+      "DeploymentName": "gpt-4o-mini",
+      "ModelName": "gpt-4o-mini",
+      "ModelVersion": "2024-07-18",
+      "SkuName": "S0",
+      "SkuCapacity": 20
+    },
+    "OpenAIChat": {
+      "ModelName": "gpt-4o-mini"
+    }
+  },
+  "AIChatService": "AzureOpenAIChat"
+}
+```
+
+#### Choose the chat completion model
+
+Set the `AIChatService` property to the chat completion model to use. Choose one from the list of available models:
+- `AzureOpenAIChat`: Azure OpenAI chat completion model.
+- `OpenAIChat`: OpenAI chat completion model.
+
+#### Configure the selected chat completion model
+
+Depending on the selected service, configure the relevant properties:
+
+`AzureOpenAIChat`:
+- `DeploymentName`: The name of the deployment that hosts the chat completion model.
+- `ModelName`: The name of the chat completion model.
+- `ModelVersion`: The version of the chat completion model.
+- `SkuName`: The SKU name of the chat completion model.
+- `SkuCapacity`: The capacity of the chat completion model.
+   
+`OpenAIChat`:  
+- `ModelName`: The name of the chat completion model.  
+
+### Text embedding model configuration
+
+The supported text embedding model configurations are located in the `AIServices` section of the `appsettings.json` file of the `ChatWithAgent.AppHost` project:
+
+```json
+{
+  "AIServices": {
+    "AzureOpenAIEmbeddings": {
+      "DeploymentName": "text-embedding-3-small",
+      "ModelName": "text-embedding-3-small",
+      "ModelVersion": "2",
+      "SkuName": "S0",
+      "SkuCapacity": 20
+    },
+    "OpenAIEmbeddings": {
+      "ModelName": "text-embedding-3-small"
+    }
+  },
+  "Rag": {
+    "AIEmbeddingService": "AzureOpenAIEmbeddings"
+  }
+}
+```
+
+#### Choose the text embedding service
+
+Set the `AIEmbeddingService` property to the text embedding service you want to use. The available services are:
+- `AzureOpenAIEmbeddings`: Azure OpenAI text embedding model.
+- `OpenAIEmbeddings`: OpenAI text embedding model.
+
+#### Configure the selected text embedding model
+
+Depending on the selected service, configure the relevant properties:
+
+`AzureOpenAIEmbeddings`:
+- `DeploymentName`: The name of the deployment that hosts the text embedding model.
+- `ModelName`: The name of the text embedding model.
+- `ModelVersion`: The version of the text embedding model.
+- `SkuName`: The SKU name of the text embedding model.`
+- `SkuCapacity`: The capacity of the text embedding model.
+
+`OpenAIEmbeddings`:
+- `ModelName`: The name of the text embedding model.
+
+### Vector store configuration
+
+The supported vector store configurations are located in the `VectorStores` section of the `appsettings.json` file of the `ChatWithAgent.AppHost` project:
+
+```json
+{
+  "VectorStores": {
+    "AzureAISearch": {
+    }
+  },
+  "Rag": {
+    "VectorStoreType": "AzureAISearch"
+  }
+}
+```
+
+Currently, only the Azure AI Search vector store is supported so there is no need to change the configuration since it is already set to `AzureAISearch` by default.
+Support for other vector stores might be added in the future.
+
+## Enable RAG
+
+The agent, by default, provides a basic, non-RAG, chat completion experience. To enable the RAG experience the following needs to be done:
+1. A vector store collection should be created and hydrated with documents that the agent will use for retrieval.
+2. The agent should be configured to use the collection for the retrieval process.
+
+### Create and hydrate a vector store collection
+
+The agent expects a vector store collection to have the following fields to be able to retrieve documents from it:
+   
+| Field Name | Data Type | Description |  
+|------------|-----------|-------------|  
+| chunk_id   | string/guid | The document key. The data type may vary depending on the vector store. |
+| chunk      | string | Chunk from the document. |  
+| title      | string | The document title or page title or page number. |  
+| text_vector | float[] | Vector representation of the chunk. |
+
+Each vector store has its own way for creating collections and filling them with documents. The following sections below describe how to do so for the supported vector stores.
+
+#### Azure AI search  
+   
+To create a collection (index in Azure AI Search), follow this [Quickstart: Vectorize text and images in the Azure portal](https://learn.microsoft.com/en-us/azure/search/search-get-started-portal-import-vectors?tabs=sample-data-storage%2Cmodel-aoai%2Cconnect-data-storage) guide.
+Use existing Azure resources, created during agent deployment, such as the Azure AI Search service, Azure OpenAI service, and the embedding model deployment instead of creating new ones.
+
+### Configure the agent to use the vector store collection
+
+To configure the agent to use the vector store collection created in the previous step, insert its name into the `CollectionName` property in the `appsettings.json` file of the `ChatWithAgent.AppHost` project:
+
+```json  
+"Rag": {
+    ... other properties ...
+    "CollectionName": "<collection name>",
+}
+```
+
+## Connection strings
+
+Some upstream dependencies require connection strings, which `azd` will prompt you for during deployment. Refer to the table below for the required formats:
+
+| Dependency | Format                         | Example                                          |
+|------------|--------------------------------|--------------------------------------------------|
+| OpenAIChat     | `Endpoint=<uri>;Key=<key>`     | `Endpoint=https://api.openai.com/v1;Key=123` or `Key=123` |
+| AzureOpenAI     | `Endpoint=<uri>;Key=<key>`     | `Endpoint=https://{account_name}.openai.azure.com;Key=123` or `Key=123` |
+| AzureAISearch     | `Endpoint=<uri>;Key=<key>`     | `Endpoint=https://{search_service}.search.windows.net;Key=123` or `Key=123` |
+
+When running agent locally, the connections string should be specified in user secrets. Please refer to the [Running the agent locally](#running-agent-locally) section for more information.
+
+
+## Running agent locally
+
+To run the agent locally, follow these steps:
+1. Right-click on the `ChatWithAgent.AppHost` project in Visual Studio and select `Set as Startup Project`.  
+2. Right-click on the `ChatWithAgent.AppHost` project in Visual Studio and select `Manage User Secrets` and add the connection strings for agent dependencies connection strings to the `ConnectionStrings` section.
+    ```json
+    {
+      "ConnectionStrings": {
+        "AzureOpenAI": "Endpoint=https://{account_name}.openai.azure.com",
+        "AzureAISearch": "Endpoint=https://{search_service}.search.windows.net"
+      }
+    }
+    ```
+    The format for connection strings can be found in the [Connection Strings](#connection-strings) section above.
+
+3. Go to the `Access control(IAM)` tab in the Azure OpenAI service on the Azure portal. Assign the `Cognitive Services OpenAI Contributor` role to the user authenticated with Azure CLI. This allows the agent to access the service on the user's behalf.
+4. Go to the `Access control(IAM)` tab in the Azure AI Search service on the Azure portal. Assign the `Search Index Data Contributor` role to the user authenticated with Azure CLI. This allows the agent to access the service on the user's behalf.
+5. Press `F5` to run the project.
+
+## Clean up the resources
+
+Run the `azd down` command, to clean up the resources. This command will delete all the resources provisioned for the agent.
+ 
+## Billing
+
+Visit the *Cost Management + Billing* page in Azure Portal to track current spend. For more information about how you're billed, and how you can monitor the costs incurred in your Azure subscriptions, visit [billing overview](https://learn.microsoft.com/azure/developer/intro/azure-developer-billing).
+
+## Troubleshooting
+
+Q: I visited the service endpoint listed, and I'm seeing a blank page, a generic welcome page, or an error page.
+
+A: Your service may have failed to start, or it may be missing some configuration settings. To investigate further:
+
+1. Run `azd show`. Click on the link under "View in Azure Portal" to open the resource group in Azure Portal.
+2. Navigate to the specific Container App service that is failing to deploy.
+3. Click on the failing revision under "Revisions with Issues".
+4. Review "Status details" for more information about the type of failure.
+5. Observe the log outputs from Console log stream and System log stream to identify any errors.
+6. If logs are written to disk, use *Console* in the navigation to connect to a shell within the running container.
+
+For more troubleshooting information, visit [Container Apps troubleshooting](https://learn.microsoft.com/azure/container-apps/troubleshooting).

+# Semantic Kernel - Amazon Bedrock Models Demo
+
+This program demonstrates how to use the Semantic Kernel using the AWS SDK for .NET with Amazon Bedrock Runtime to 
+perform various tasks, such as chat completion, text generation, and the streaming versions of these services. The
+BedrockRuntime is a managed service provided by AWS that simplifies the deployment and management of large language
+models (LLMs).
+
+## Authentication
+
+The AWS setup library automatically authenticates with the BedrockRuntime using the AWS credentials configured 
+on your machine or in the environment.
+
+### Setup AWS Credentials
+
+If you don't have any credentials configured, you can easily setup in your local machine using the [AWS CLI tool](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html) following the commands below after installation
+
+```powershell
+> aws configure 
+AWS Access Key ID [None]: Your-Access-Key-Here
+AWS Secret Access Key [None]: Your-Secret-Access-Key-Here
+Default region name [None]: us-east-1 (or any other)
+Default output format [None]: json
+```
+
+With this property configured you can run the application and it will automatically authenticate with the AWS SDK.
+
+## Features
+
+This demo program allows you to do any of the following:
+- Perform chat completion with a selected Bedrock foundation model. 
+- Perform text generation with a selected Bedrock foundation model. 
+- Perform streaming chat completion with a selected Bedrock foundation model. 
+- Perform streaming text generation with a selected Bedrock foundation model.
+
+## Usage
+
+1. Run the application.
+2. Choose a service option from the menu (1-4). 
+   - For chat completion and streaming chat completion, enter a prompt and continue with the conversation.
+   - For text generation and streaming text generation, enter a prompt and view the generated text.
+3. To exit chat completion or streaming chat completion, leave the prompt empty.
+   - The available models for each task are listed before you make your selection. Note that some models do not support
+   certain tasks, and they are skipped during the selection process.

+# Native-AOT Samples
+This application demonstrates how to use the Semantic Kernel Native-AOT compatible API in a Native-AOT application.
+
+## Running Samples
+The samples be run either in a debug mode by just setting a break point and pressing `F5` in Visual Studio (make sure the `AotCompatibility` project is set as the startup project) in which case they are run in a regular CoreCLR application and not in Native-AOT one. This might be useful to understand how the API works and how to use it.
+
+To run the samples in a Native-AOT application, first publish it using the following command: `dotnet publish -r win-x64`. Then, execute the application by running the following command in the terminal: `.\bin\Release\net8.0\win-x64\publish\AotCompatibility.exe`.  
+
+## Samples
+Most of the samples don't require any additional setup, and can be run as is. However, some of them might require additional configuration.
+
+### 1. [ONNX Chat Completion Service](./OnnxChatCompletionSamples.cs)
+To configure the sample, you need to download the ONNX model from the Hugging Face repository. Go to a directory of your choice where the model should be downloaded and run the following command:
+```powershell
+git clone https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx
+```
+
+> [!IMPORTANT]
+The `Phi-3` model may be too large to download using the `git clone` command unless you have the [git-lfs extension](https://git-lfs.com/) installed. 
+You might need to download it manually using the following link: [Phi-3-Mini-4k CPU](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct-onnx/resolve/main/cpu_and_mobile/cpu-int4-rtn-block-32/phi3-mini-4k-instruct-cpu-int4-rtn-block-32.onnx.data?download=true) (approximately 2.7 GB).
+
+After downloading the model, you need to configure the sample by setting the `Onnx:ModelPath` and `Onnx:ModelId` secrets. 
+The `Onnx:ModelPath` should point to the directory where the model was downloaded, and the `Onnx:ModelId` should be set to `phi-3`.
+The secrets can be set using [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets#secret-manager) in the following way:
+```powershell
+dotnet user-secrets set "Onnx:ModelId" "phi-3"
+dotnet user-secrets set "Onnx:ModelPath" "C:\path\to\huggingface\Phi-3-mini-4k-instruct-onnx\cpu_and_mobile\cpu-int4-rtn-block-32" 
+```
+
+### AOT Compatibility
+At the moment, the following Semantic Kernel packages are AOT compatible:
+
+| Package                   | AOT compatible |  
+|--------------------------|----------------|  
+| SemanticKernel.Abstractions | ✔️              |  
+| SemanticKernel.Core         | ✔️              |  
+| Connectors.Onnx            | ✔️              |  
+
+Other packages are not AOT compatible yet, but we plan to make them compatible in the future.

+# Booking Restaurant - Demo Application
+
+This sample provides a practical demonstration of how to leverage features from the [Semantic Kernel](https://learn.microsoft.com/en-us/semantic-kernel) to build a console application. Specifically, the application utilizes the [Business Schedule and Booking API](https://www.microsoft.com/en-us/microsoft-365/business/scheduling-and-booking-app) through Microsoft Graph to enable a Large Language Model (LLM) to book restaurant appointments efficiently. This guide will walk you through the necessary steps to integrate these technologies seamlessly.
+
+## Semantic Kernel Features Used
+
+- [Plugin](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/Functions/KernelPlugin.cs) - Creating a Plugin from a native C# Booking class to be used by the Kernel to interact with Bookings API.
+- [Chat Completion Service](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/IChatCompletionService.cs) - Using the Chat Completion Service [OpenAI Connector implementation](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/Connectors/Connectors.OpenAI/Services/OpenAIChatCompletionService.cs) to generate responses from the LLM.
+- [Chat History](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/src/SemanticKernel.Abstractions/AI/ChatCompletion/ChatHistory.cs) Using the Chat History abstraction to create, update and retrieve chat history from Chat Completion Models.
+- [Auto Function Calling](https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/Concepts/ChatCompletion/OpenAI_FunctionCalling.cs) Enables the LLM to have knowledge of current importedUsing the Function Calling feature automatically call the Booking Plugin from the LLM.
+
+## Prerequisites
+
+- [.NET 10](https://dotnet.microsoft.com/download/dotnet/10.0).
+- [Microsoft 365 Business License](https://www.microsoft.com/en-us/microsoft-365/business/compare-all-microsoft-365-business-products) to use [Business Schedule and Booking API](https://www.microsoft.com/en-us/microsoft-365/business/scheduling-and-booking-app).
+- [Azure Entra Id](https://www.microsoft.com/en-us/security/business/identity-access/microsoft-entra-id) administrator account to register an application and set the necessary credentials and permissions.
+
+### Function Calling Enabled Models
+
+This sample uses function calling capable models and has been tested with the following models:
+
+| Model type      | Model name/id             |       Model version | Supported |

+ℹ️ OpenAI Models older than 0613 version do not support function calling.
+
+ℹ️ When using Azure OpenAI, ensure that the model name of your deployment matches any of the above supported models names.
+
+## Configuring the sample
+
+The sample can be configured by using the command line with .NET [Secret Manager](https://learn.microsoft.com/en-us/aspnet/core/security/app-secrets) to avoid the risk of leaking secrets into the repository, branches and pull requests.
+
+### Create an App Registration in Azure Active Directory
+
+1. Go to the [Azure Portal](https://portal.azure.com/).
+2. Select the Azure Active Directory service.
+3. Select App registrations and click on New registration.
+4. Fill in the required fields and click on Register.
+5. Copy the Application **(client) Id** for later use.
+6. Save Directory **(tenant) Id** for later use..
+7. Click on Certificates & secrets and create a new client secret. (Any name and expiration date will work)
+8. Copy the **client secret** value for later use.

+# Semantic Kernel - Code Interpreter Plugin with Azure Container Apps
+
+This example demonstrates how to do AI Code Interpretetion using a Plugin with Azure Container Apps to execute python code in a container.
+
+## Create and Configure Azure Container App Session Pool  
+   
+1. Create a new Container App Session Pool using the Azure CLI or Azure Portal.
+2. Specify "Python code interpreter" as the pool type.
+3. Add the following roles to the user that will be used to access the session pool:
+   - The `Azure ContainerApps Session Executor` role to be able to create and manage sessions.
+   - The `Container Apps SessionPools Contributor` role to be able to work with files.
+
+## Configuring Secrets
+
+The example require credentials to access OpenAI and Azure Container Apps (ACA)
+
+If you have set up those credentials as secrets within Secret Manager or through environment variables for other samples from the solution in which this project is found, they will be re-used.
+
+### To set your secrets with Secret Manager:
+
+```
+dotnet user-secrets init
+
+dotnet user-secrets set "OpenAI:ApiKey" "..."
+dotnet user-secrets set "OpenAI:ChatModelId" "gpt-3.5-turbo" # or any other function callable model.
+
+dotnet user-secrets set "AzureContainerAppSessionPool:Endpoint" " .. endpoint .. "
+```
+
+### To set your secrets with environment variables
+
+Use these names:
+
+```
+# OpenAI
+OpenAI__ApiKey
+OpenAI__ChatModelId
+
+# Azure Container Apps
+AzureContainerAppSessionPool__Endpoint
+```
+
+### Usage Example
+
+User: Upload the file c:\temp\code-interpreter\test-file.txt
+
+Assistant: The file test-file.txt has been successfully uploaded.
+
+User: How many files I have uploaded ?
+
+Assistant: You have uploaded 1 file.
+
+User: Show me the contents of this file
+
+Assistant: The contents of the file "test-file.txt" are as follows:
+
+```text
+the contents of the file
+```
