Elect.DI

Author Top Nguyen

Overview

• Managing Dependency Injection in .NET Core.

• I have seen some situations where a web project has a Startup.cs that is hundreds/thousands lines with services.AddTransient services.AddScoped services.AddSingleton calls for every single interface and implementation.

• With Elect.DI, you can register dependency injection by Attributes - lifetime define in the Implementaion class and just 1 line of code in Startup.cs to enable Scanner and auto register follow attribute setup.

• Elect.DI support to auto register Service and Implementation by

  • Projects reference.
  • Scan assemblies in difference folders.

Installation

• Package Manager

  PM> Install-Package Elect.DI
  

• .NET CLI

  dotnet add package Elect.DI
  

See more information in .

Usage

• Startup.cs: add Scanner - Auto register dependency injection.

  public void ConfigureServices(IServiceCollection services)
  {
      // Auto Register Dependency Injection
      services.AddElectDI();
      
  //  services.AddElectDI(_ =>
  //  {
  //      _.ListAssemblyName = new List<string> // default is 1 assembly name: application name - Elect.Sample.DI
  //      {
  //          "ExampleAssembly" // will scan ExampleAssembly.dll and ExampleAssembly.*.dll
  //      };
  //      _.ListAssemblyFolderPath = new List<string> // default is  1 folder: application base folder path
  //      {
  //          "C:\\ExampleAssemblyFolderPath" 
  //      };
  //  });
  
      // Optional - Print out Registered Service with Information
      services.PrintServiceAddedToConsole();
  }

• Define lifetime in implementation

  public interface ISampleService{
  
  }
  
  [ScopedDependency(ServiceType = typeof(ISampleService))]
  public class SampleService : ISampleService{
  }

  • ScopedDependency: Register as Scoped Lifetime.
  • TransientDependency: Register as Transient Lifetime.
  • SingletonDependency: Register as Singleton Lifetime.
  • Register for Interface via parameter ServiceType, if not set parameter value then the Implementation injection it self.
