Create a gRPC service

dotnet new grpc -o GrpcGreeter
code -r GrpcGreeter

dotnet dev-certs https --trust

CTRL+F5

Create a gRPC client

dotnet add GrpcGreeterClient.csproj package Grpc.Net.Client
dotnet add GrpcGreeterClient.csproj package Google.Protobuf

dotnet add GrpcGreeterClient.csproj package Grpc.Tools


Copy the Protos\greet.proto from the server.
edit: option csharp_namespace = "GrpcGreeterClient";

Edit: GrpcGreeterClient.csproj
<ItemGroup>

    <Protobuf Include="Protos\greet.proto" GrpcServices="Client" /> </ItemGroup>

Edit: Program.cs

using System;

using System.Threading.Tasks;

using Grpc.Net.Client;

namespace GrpcGreeterClient

            // The port number(5001) must match the port of the gRPC server.

            using var channel = GrpcChannel.ForAddress("https://localhost:5001");

            var client = new Greeter.GreeterClient(channel);
