This folder contains examples demonstrating how to create and use agents with the A2A (Agent2Agent) protocol from the `agent_framework` package to communicate with remote A2A agents.

## Quick Testing with .NET A2A Servers

For quick testing and demonstration, you can use the pre-built .NET A2A servers from this repository:

**Quick Testing Reference**: Use the .NET A2A Client Server sample at:
`..\agent-framework\dotnet\samples\A2AClientServer`

### Run Python A2A Sample
