Allow Integration with ASP.Net Core

Is your feature request related to a problem? Please describe.
Many teams have already working APIs in place which are built using ASP.Net Core Controllers or Minimal APIs. It would be good to provide an easy way to leverage these APIs and expose them through the MCP.

Describe the solution you'd like
Since ASP.Net Core already has the API Explorer built in which allows looking at the metadata of endpoints, it could be as easy as providing a Middleware which would then generate the MCP description at the /resources/list endpoint.
Another Middleware could then listen at the /message endpoint and dispatch the calls to the appropriate Controller / Minimal Endpoint.

Describe alternatives you've considered
None

Additional context
The MCP spec has just introduces "normal" HTTP calls without SSE
https://github.com/modelcontextprotocol/specification/pull/206

Inizia esaminando i metadati di ASP.NET Core API Explorer e le normali chiamate HTTP della specifica MCP. Definisci come il middleware genererebbe le descrizioni MCP in /resources/list e inoltrerebbe le chiamate da /message a Controllers o Minimal APIs. Il lavoro sarà considerato completato quando sarà disponibile un design di integrazione concordato, con l’ambito dell’implementazione e la copertura di entrambi gli stili di endpoint.
