Incorporate .WithHttpTransport and .MapMcp into the AspNetCore project

[MCKRUZ]

Can the AspNetCore project that used to be for SSE be updated with the new .WithHttpTransport and .MapMcp protocols. I am currently unable to get these working with the current code.

They're there...

Can you elaborate on what's not working?

Oh totally agree that the code to "do" it is available. The issue I'm having is that there are no "example" projects out there. In trying to get it to work I'm running into issues. I could post them here if you are willing to help troubleshoot. I just figured it might be easier to alter the demos to include these features since SSE is deprecated.

Thanks. It is generally easier to start from a small example when creating issue repros rather than asking us to troubleshoot a complicated project.

Feel free to alter the demo at https://github.com/modelcontextprotocol/csharp-sdk/blob/4043538285ed4324e0aed203dad0eaf73f31fa38/samples/AspNetCoreSseServer/Program.cs to repro any issues you are running into. It already supports both the SSE (at http://localhost:3001/sse) and Streamable HTTP transports (at http://localhost:3001/).
