Dynamic Dependency Injections

Default implementation of dynamic dependency injections in ASP.NET Core project

Namespace

using Microsoft.Extensions.DependencyInjection.DynamicInjection

Code Syntax

• If your project is single

   public void ConfigureServices(IServiceCollection services)
   {
      services.AddServicesOfType<IScopedService>();
      services.AddServicesAttributeOfType<ScopedServiceAttribute>();      
   }
  

• If your project is multiple

    public void ConfigureServices(IServiceCollection services)
    {
        //Assemblies start with "Demo.DynamicInjections", "Demo.Repository", "Demo.Manager" will only be scanned.
        string[] assembliesToBeScanned = new string[] { "Demo.DynamicInjections", "Demo.Manager", "Demo.Repository" };
        services.AddServicesOfType<IScopedService>(assembliesToBeScanned);
        services.AddServicesAttributeOfType<ScopedServiceAttribute>(assembliesToBeScanned);
    }
  

• Every interface can hold attribute- Scoped Service

  [ScopedService]
  public interface IStudentService
  {
      List<Student> GetStudents();
  }
  

• As usual calling code

  public class StudentController : Controller
  {
      private readonly IStudentService _studentService;
  
      public StudentController(IStudentService studentService)
      {
          _studentService = studentService;
      }
  
      public IActionResult Index()
      {
          var studentsByService = _studentService.GetStudents();
  
          return View();
      }
  }
