 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();
        }
    }

Software Development

Software Development Agile Agile is an insurance policy for market changes. By designing your solution according to this methodology, your project remains flexible and is always ready for change. It is always better to correct the mistake early in the process. With this method, you keep your finger on the pulse of a dynamic market and changing user expectations. As a result, you can continuously adapt, change your strategy, and create a product that will be in demand by the target audience, even if preferences have changed during the development process. DevOps DevOps is one more way to optimize the development budget of your application. A key DevOps approach is that this practice and its culture allow team members to better interact with each other and the customer. The software development team and those responsible for the operation of the application share responsibilities clearly, and it helps you avoid shifting responsibilities from one team member to another. DevOps involves th...

Abstract Factory Pattern

Abstract Factory Pattern  Gamma Categorization: Creational Design Patten Summary: When the object construction is complicated, needing multiple arguments, we should create a separate function (Factory Method) or class (Factory), which is responsible for the creation of the all object. Problem examples Suport of multiple databases Multiple data sources: Serial port, ethernet port, device driver Diferent report types Solution Abstract class Generalized interface A Factory creates instances of the concrete classes Sample Code The abstract factory public   interface   IPhotoFactory {      IAnaloguePhoto   CreateAnaloguePhoto ();      IDigitalPhoto   CreateDigitalPhoto (); } The abstract products public   interface   IAnaloguePhoto {      string   GetName (); } public   interface   IDigitalPhoto {      ...

Template Pattern

Template Pattern  Gamma Categorization: Behavioral Design Pattern Summary:  Define the skeleton of an algorithm in an operation, deferring some steps to subclasses. Template Method lets subclasses redefine certain steps of an algorithm without changing the algorithm's structure. Sample Code Problem: We want to have a digital camera template, which should be used or overriden by it's concrete classes. Code public   abstract   class   DigitalCamera {      public   void   TakePhoto ()     {          System . Console . WriteLine ( "Taking photo." );     }      public   abstract   void   LiveView ();      public   virtual   void   FireFlash ()     {          System . Console . WriteLine...
