gRPC in .NET Core

 gRPC in .NET Core

Source: https://docs.microsoft.com/en-us/aspnet/core/tutorials/grpc/grpc-start?view=aspnetcore-5.0&tabs=visual-studio-code

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
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // 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);
            var reply = await client.SayHelloAsync(new HelloRequest { Name = "GreeterClient" });
            Console.WriteLine("Greeting: " + reply.Message); Console.WriteLine("Press any key to exit...");
            Console.ReadKey();
        }
    }

SOLID (4/5) - Interface segregation principle

Interface segregation principle In the field of software engineering, the interface-segregation principle (ISP) states that no client should be forced to depend on methods it does not use. ISP splits interfaces that are very large into smaller and more specific ones so that clients will only have to know about the methods that are of interest to them. Such shrunken interfaces are also called role interfaces. ISP is intended to keep a system decoupled and thus easier to refactor, change, and redeploy. using   System ; namespace   interfacesegregation {      public   class   Document       {     }      public   interface   IMachine       {          void   Print ( Document   d );          void   Scan ( Document   d );     ...
