protobuf-net.Connect.AspNetCore

Serves the Connect protocol from ASP.NET Core — the cross-language protocol with implementations for Go, TypeScript, Swift and others, so these endpoints are callable from any of them.

Documentation: connect.protobuf-net.dev

builder.Services.AddMyServices();   // generated from [ProtoConnect]
var app = builder.Build();
app.BindMyServices();               // one endpoint per method

All four method shapes: unary, client-streaming, server-streaming and bidirectional. Binds to HttpContext and endpoint routing rather than to Kestrel, so Kestrel, HTTP.sys, IIS and TestServer all work from one implementation.

Each method becomes its own endpoint, so [Authorize], CORS policies, rate limiting and output caching attach per RPC — ASP.NET Core resolves those from the matched endpoint, in middleware that runs before any handler. On the code-first path those attributes are carried from your implementation without reflecting: they are reconstructed at build time and emitted into the binding. (Contract-first is the exception — there is no generator in that path, so the attributes are passed explicitly; see the docs.)

Only full-duplex bidirectional streaming needs HTTP/2. Everything else — including half-duplex bidi — works over plaintext HTTP/1.1, because Connect carries trailing metadata in the body rather than in HTTP trailers. That is the operational argument for Connect over gRPC.

A contract-first service needs no generator and no attribute:

builder.Services.AddConnect(o => o.Codecs.Add(MarshallerConnectCodec.Instance));
app.MapConnectService<GreeterImpl>(Greeter.BindService);   // protoc's own method group

⚠️ On that path [Authorize] is not inferred — this deliberately does not reflect. Chain .RequireAuthorization(...) or pass metadata; the analyzer PBN5007 warns if you do neither.
