The managed hosting layer handles compute scaling, session state, a dedicated Microsoft Entra identity, an OpenAI-compatible /responses endpoint, telemetry via Application Insights, agent evaluators, and immutable versioning for rollbacks. The post walks through testing locally with azd ai agent run/invoke, then shipping to production, plus a VS Code extension (Microsoft Foundry Toolkit) that automates scaffolding, debugging, and deployment. Hosted Agents is now generally available.

Add the Microsoft.Agents.AI.Foundry.Hosting NuGet package, then add three lines of C# code: AgentHost.CreateBuilder(args) to create the host, builder.Services.AddFoundryResponses(agent) to register the agent, and builder.RegisterProtocol("responses", endpoints => endpoints.MapFoundryResponses()) to expose the /responses endpoint. Then run azd provision followed by azd deploy to ship it to Microsoft Foundry Agent Service. daily.dev surfaces practical walkthroughs like this for teams moving agent prototypes into production. What does Microsoft Foundry Hosted Agents manage automatically for a deployed agent? Foundry Hosted Agents provision compute per session and scale to zero when idle, persist session state including $HOME and uploaded files across turns, create a dedicated Microsoft Entra ID identity per agent for secure access, and expose an OpenAI-compatible /responses endpoint usable from any compatible SDK. They also inject OpenTelemetry tracing and Application Insights automatically, with no manual configuration required. developers evaluating managed agent hosting can track these platform capabilities on daily.dev. How do I test a Foundry Hosted Agent locally before deploying it? Install the azd AI agent extension with azd ext install azure.ai.agents, scaffold the project with azd ai agent init, set the FOUNDRY\_PROJECT\_ENDPOINT and AZURE\_AI\_MODEL\_DEPLOYMENT\_NAME environment variables, then run azd ai agent run to start the host on localhost:8088\. Invoke it locally with azd ai agent invoke --local or a curl POST to the /responses endpoint. anyone wiring up local agent testing loops can keep tabs on tooling updates like this via daily.dev. 1.7K Impressions2 Upvotes Comment Bookmark Copy Share your thoughtsPost [](https://daily.dev/sources/dotnet) [.NET Blog](https://daily.dev/sources/dotnet "https://daily.dev/sources/dotnet") dotnet offers insights into .NET development, C# programming language, and cross-platform applicatio...
