gRPC-request-net-core.cs

// .NET Core 3.x
// To use gRPC without TLS following switch must be set before creating the GrpcChannel/HttpClient.
// AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);

var options = new GrpcChannelOptions();
var channel = GrpcChannel.ForAddress("https://localhost:5001", options);
var client = new FooService.FooServiceClient(channel);

// Asynchronous unary RPC
var foosRequest = new FooRequest { Message = "Sample request" };
var fooResponse = await client.GetFooAsync(foosRequest);

Console.WriteLine($"\t{fooResponse.Message}");
