Investigation of how to orchestrate an agentic system using an A2A protocol based on .NET primitives and create a PoC. Use Case: We have existing agents that support A2A, and we want to build it into a multi-agent system.
Protocol
Let's start from theory. The agent-to-agent (A2A) protocol is designed to define well-known contracts for communication between agents without humans. Every agent publishes an AgentCard /.well-known/agent-card.json. An Agent client discovers the card, then sends tasks to the agent as messages.
Our building blocks:
AgentCard - what the agent can do
