GrpcEmbed

<p align="center"> <img src="assets/grpcembed-icon.png" width="160" alt="GrpcEmbed icon" /> </p>

Native gRPC for existing ASP.NET Core MVC APIs.

NuGet package: DevelKit.GrpcEmbed.

CI NuGet License

Your controllers. Your contracts. Now gRPC.

GrpcEmbed adds a standard gRPC/Protocol Buffers transport to compatible MVC actions. It does not replace REST, invent an RPC protocol, use JSON in the gRPC path, or require generated protobuf DTOs.

builder.Services.AddControllers();
builder.Services.AddGrpcEmbed();

app.MapControllers();
app.MapGrpcEmbed();

An ordinary UsersController.Get(int id) remains available as GET /api/users/42 and is additionally exposed as /GrpcEmbed.Users/Get.

Client

services.AddGrpcEmbedClient<IUsersApi>(options =>
{
    options.Address = new Uri("https://users-service");
    options.DefaultTimeout = TimeSpan.FromSeconds(10);
    options.TransportMode = GrpcEmbedTransportMode.GrpcOnly;
});

var user = await users.Get(42, cancellationToken);

Schema and reflection are disabled by default for production safety. Enable them explicitly during development:

builder.Services.AddGrpcEmbed(options =>
{
    options.EnableSchemaEndpoint = true;
    options.EnableReflection = true;
    options.SchemaAuthorizationPolicy = "SchemaReaders"; // optional named authorization policy
});

This exposes /_grpcembed/schema.proto, /_grpcembed/descriptor.pb, /_grpcembed/schema.json, a deterministic schema hash at /_grpcembed, and standard grpc.reflection.v1alpha.ServerReflection. Set SchemaManifestPath to a checked-in manifest to detect removed, renumbered, renamed, or type-changed fields during startup. Clients may set ExpectedSchemaHash for strict contract negotiation.

For deliberate schema evolution, use [GrpcFieldNumber(n)] to preserve a field or parameter wire ID across a rename, and [GrpcReservedField(n)] on DTO types when removing fields. Reserved numbers are emitted into both .proto and the binary descriptor set.

Current milestone

The repository contains runtime MVC discovery, cached dynamic contracts and accessors, deterministic field numbers, protobuf-net marshalling, standard native unary gRPC registration, controller DI activation, cancellation, authorization metadata, authorization/resource/action/result/exception filters, parameter and DTO validation, status mapping, schema/descriptor export, reflection, and an interface proxy. MVC binding-source metadata is retained for discovery and schema tooling; values on the gRPC path come from the protobuf request rather than MVC route/query/body value providers.

Version 1 intentionally implements unary RPC only. Custom MVC model binders, formatter-specific results, streaming, trimming and NativeAOT are not supported. Reflection.Emit and DispatchProxy are explicitly annotated with trimming/dynamic-code warnings so unsupported deployments fail visibly during analysis.
