A basic test of the gRPC implementation for C# 10 on dotnet6

Steps

• In Visual Studio creat a gRPC progect

Server

• add new item > protobuf.proto and write the proto3 interface of the service design
• In .proj file add <Protobuf Include="Protos\pin.proto" GrpcServices="Server" /> to the ItemGroup. This is how the compiler knows the existence of the proto api definition file, and thereby using it to generate c# abstraction codes.
• build to generate the abstractions. They can be found in obj\Debug\net6.0\Protos
• In Program.cs ensure services.AddGrpc(); and endpoints.MapGrpcService<PinService>();

Client

• Install the following packages Grpc.Tools, Grpc.Net.Client and Google.Protobuf
• On the client, copy the proto file from the service and rename the namespace according to the client namespace.
• In .proj file add <Protobuf Include="Protos\pin.proto" GrpcServices="Client" /> to the ItemGroup. Take note that here the GrpcServices value is set to Client.
• Below is a sample request with a console app:

using var channel = GrpcChannel.ForAddress("https://localhost:7063");

var pinService = new PinVending.PinVendingClient(channel);
var response = pinService.GetToken(new ApiClient 
{
    ApiKey = "1254785693254",
    BusinessName = "Infinity Tech"
});

Console.WriteLine("Get Token: " + response.Result);
