![]() ![]() NET Core gRPC client and server in ASP.NET Core Similarly, the attribute is set to Client in client projects. To ensure only the server assets are generated in a server project, the GrpcServices attribute is set to Server. New HelloRequest ) Ĭonsole.WriteLine("Greeting: " + reply.Message) Ĭonsole.WriteLine("Press any key to exit.") īy default, server and client assets are generated for each. Using var channel = GrpcChannel.ForAddress(" var client = new Greeter.GreeterClient(channel) ![]() The port number must match the port of the gRPC server. Call GreeterClient.SayHelloAsync to initiate a gRPC call to the server. For the greet.proto, the example described previously, a concrete GreeterClient type is generated. proto file are translated into methods on the concrete type, which can be called. Public override Task SayHello(HelloRequest request, ServerCallContext context)įor client-side assets, a concrete client type is generated. public class GreeterService : Greeter.GreeterBase A concrete implementation GreeterService overrides the method and implements the logic handling the gRPC call. For the greet.proto, the example described previously, an abstract GreeterBase type that contains a virtual SayHello method is generated. Create a concrete service implementation that derives from this base type and implements the logic for the gRPC calls. The base type contains the definitions of all the gRPC calls contained in the. proto files.įor server-side assets, an abstract service base type is generated. The tooling package generates the C# types representing the messages defined in the included. Runtime build native contentfiles analyzers buildtransitive The tooling package isn't required at runtime, so the dependency is marked with PrivateAssets="All": Server projects can add Grpc.AspNetCore using the Package Manager in Visual Studio or by adding a to the project file: Ĭlient projects should directly reference Grpc.Tools alongside the other packages required to use the gRPC client. The Grpc.AspNetCore metapackage includes a reference to Grpc.Tools. This package is required by both the server and client projects.
