Jacob Alber e8f1f4e785 fix: Fix Checkpoint Restore when Rehydrating Run (#642)
When checkpointing we did not persist the set of instantiated executors. This means, in turn, when we restore from a checkpoint when using Resume(Stream) rather than restoring a checkpoint in the context of an already existing (Streaming)Run, the executors never got reinstantiated and there were no executors to notify that a state should be loaded.

The fix is to ensure we persist the list and reinstantiate the executors on rehydration.

* Also adds a rehydration restore test

Get Started with Microsoft Agent Framework for C# Developers

Run the Minimal Console demo

The Minimal Console demo is a simple console application which shows how to create and run an agent.

Supported Platforms:

  • .Net: net9.0, net8.0, netstandard2.0, net472
  • OS: Windows, macOS, Linux

If you want to use the latest published packages following the instructions here.

1. Configure required environment variables

This samples uses Azure OpenAI by default so you need to set the following environment variable

$env:AZURE_OPENAI_ENDPOINT = "https://<your deployment>.openai.azure.com/"

If you want to use OpenAI

  1. Edit Program.cs and change the following lines:
    AIAgent agent = new AzureOpenAIClient(
      new Uri(Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT")!),
      new AzureCliCredential())
       .GetChatClient("gpt-4o-mini")
       .CreateAIAgent(
         instructions: "You are a helpful assistant, you can help the user with weather information.",
         tools: [AIFunctionFactory.Create(GetWeather)]);
    
    To this:
    AIAgent agent = new OpenAIClient(Environment.GetEnvironmentVariable("OPENAI_API_KEY")!)
      .GetChatClient("gpt-4o-mini")
      .CreateAIAgent(
        instructions: "You are a helpful assistant, you can help the user with weather information.",
        tools: [AIFunctionFactory.Create(GetWeather)]);
    
  2. Create an environment variable with your OpenAI key
    $env:OPENAI_API_KEY = "sk-..."
    

2. Build the project

cd demos\MinimalConsole
dotnet build

3. Run the demonstration

dotnet run --framework net9.0 --no-build

Sample output:

The weather in Amsterdam is currently cloudy, with a high temperature of 15°C.
