Jaliya's Blog: Microsoft Agent Framework: Hosted Agents in Microsoft Foundry with .NET

A hands-on walkthrough demonstrates hosting an AI agent built with Microsoft Agent Framework as a Foundry hosted agent in .NET, contrasting it with self-hosting (Azure Functions) and prompt agents. The agent code, tools, and dependencies run entirely inside a Foundry-managed container with its own Microsoft Entra identity, endpoint, versioning, and playground. Steps cover writing the agent, running it locally on port 8088, deploying with the Azure Developer CLI and Foundry extension, invoking the deployed agent, calling it from code via ProjectResponsesClient, and cleanly deleting it via REST with force=true to cascade session cleanup. Notes a versioning mismatch gotcha between the azure.yaml manifest (2.0.0) and docs examples (1.0.0) that must align with the Microsoft.Agents.AI.Foundry.Hosting package.
