 The ASP.NET Core integration supports SSE transport alongside Streamable HTTP. The same `MapMcp()` endpoint handles both protocols — clients connecting with SSE are automatically served using the legacy SSE mechanism:
 
-```csharp
-var builder = WebApplication.CreateBuilder(args);
-
-builder.Services.AddMcpServer()
-    .WithHttpTransport()
-    .WithTools<MyTools>();
-
-var app = builder.Build();
-app.MapMcp(); // Handles both Streamable HTTP and SSE clients
-app.Run();
-```
-
 No additional configuration is needed. When a client connects using the SSE protocol, the server responds with an SSE stream for server-to-client messages and accepts client-to-server messages via a separate POST endpoint.
