Prerequisites
⚠️ WARNING: Container Recommendation
GitHub Copilot can execute tools and commands that may interact with your system. For safety, it is strongly recommended to run this sample in a containerized environment (e.g., Docker, Dev Container) to avoid unintended consequences to your machine.
Before you begin, ensure you have the following prerequisites:
- .NET 10 SDK or later
- GitHub Copilot CLI installed and available in your PATH (or provide a custom path)
Setting up GitHub Copilot CLI
To use this sample, you need to have the GitHub Copilot CLI installed. You can install it by following the instructions at: https://github.com/github/copilot-sdk
Once installed, ensure the copilot command is available in your PATH, or configure a custom path using CopilotClientOptions.
Running the Sample
No additional environment variables are required if using default configuration. The sample will:
- Create a GitHub Copilot client with default options
- Create an AI agent using the Copilot SDK
- Send a message to the agent
- Display the response
Run the sample:
dotnet run
Advanced Usage
You can customize the agent by providing additional configuration:
using GitHub.Copilot.SDK;
using Microsoft.Agents.AI;
// Create and start a Copilot client
await using CopilotClient copilotClient = new();
await copilotClient.StartAsync();
// Create session configuration with specific model
SessionConfig sessionConfig = new()
{
Model = "claude-opus-4.5",
Streaming = false
};
// Create an agent with custom configuration using the extension method
AIAgent agent = copilotClient.AsAIAgent(
sessionConfig,
ownsClient: true,
id: "my-copilot-agent",
name: "My Copilot Assistant",
description: "A helpful AI assistant powered by GitHub Copilot"
);
// Use the agent - ask it to write code for us
AgentResponse response = await agent.RunAsync("Write a small .NET 10 C# hello world single file application");
Console.WriteLine(response);
Streaming Responses
To get streaming responses:
await foreach (AgentResponseUpdate update in agent.RunStreamingAsync("Write a C# function to calculate Fibonacci numbers"))
{
Console.Write(update.Text);
}
