# Process Framework with .NET Aspire
|
|
|
|
This demo illustrates how the [Semantic Kernel Process Framework](https://learn.microsoft.com/semantic-kernel/overview) can be integrated with [.NET Aspire](https://learn.microsoft.com/dotnet/aspire/get-started/aspire-overview). The Process Framework enables the creation of business processes based on events, where each process step may invoke an agent or execute native code.
|
|
|
|
In the demo, agents are defined as **external services**. Each process step issues an HTTP request to call these agents, allowing .NET Aspire to trace the process using **OpenTelemetry**. Furthermore, because each agent is a standalone service, they can be restarted independently via the .NET Aspire developer dashboard.
|
|
|
|
## Architecture
|
|
|
|
The business logic of this sample is straightforward: it defines a process that translates text from English and subsequently summarizes it.
|
|
|
|
|
|
|
|
## What is .NET Aspire?
|
|
|
|
.NET Aspire is a set of tools, templates, and packages for building observable, production ready apps. .NET Aspire is delivered through a collection of NuGet packages that bootstrap or improve common challenges in modern app development.
|
|
Key features include:
|
|
|
|
- Dev-Time Orchestration: provides features for running and connecting multi-project applications, container resources, and other dependencies for local development environments.
|
|
- Integrations: offers standardized NuGet packages for frequently used services such as Redis and Postgres, with standardized interfaces ensuring they consistent and seamless connectivity.
|
|
- Tooling: includes project templates and tools for Visual Studio, Visual Studio Code, and the .NET CLI to help creating and interacting with .NET Aspire projects.
|
|
|
|
.NET Aspire orchestration assists with the following concerns:
|
|
|
|
- App composition: specify the .NET projects, containers, executables, and cloud resources that make up the application.
|
|
- Service Discovery and Connection String Management: automatically injects the right connection strings, network configurations, and service discovery information to simplify the developer experience.
|
|
|
|
### Running with .NET Aspire
|
|
|
|
To run this sample with .NET Aspire, clone the repository and execute the following commands:
|
|
|
|
```bash
|
|
cd scr/ProcessFramework.Aspire/ProcessFramework.Aspire.AppHost
|
|
dotnet run
|
|
```
|
|
|
|
A dashboard will then be displayed in the browser, similar to this:
|
|
|
|
|
|
By invoking the `ProcessOrchestrator` service, the process can be started. A predefined request is available in [`ProcessFramework.Aspire.ProcessOrchestrator.http``](./ProcessFramework.Aspire/ProcessFramework.Aspire.ProcessOrchestrator/ProcessFramework.Aspire.ProcessOrchestrator.http).
|
|
|
|
This will generate a trace in the Aspire dashboard that looks like this:
|
|
|
|
|
|
Additionally, the metrics for each agent can be monitored in the Metrics tab:
