AutoInjectRegister 1.2.0

AutoInjectRegister

Auto register classes and interfaces for dependency injection. Add the auto inject attribute to the top of any class file to be marked for auto injection. This will help you know the scope of each class just by looking at the class file.

For .Net and C#.

Adding Auto Inject to DI

Add to your program or startup file

 builder.Services.AutoInjectRegisterServices();

Alternatively, if you would like to be more specific with which assembly you would like added, add a type from an assembly you want added.

  builder.Services.AutoInjectRegisterServices(typeof(IDbReader), typeof(ICache), typeof(IProxy));

This will only register files in that assembly, so be aware that it won't take everything plus that assembly. It will only take the assembly specified.

Register your classes

Add the auto inject attribute to your classes in two different ways.

No paramter attribute

You will have access to three attributes.

    [AutoInjectTransient]

    [AutoInjectScoped]

    [AutoInjectsSingleton]

You can implement them like so.

    [AutoInjectTransient]
    internal class ExampleTransientClass : IExampleTransientInterface
    {
        ...
    }

    [AutoInjectScoped]
    internal class ExampleScopedClass : IExampleScopedInterface
    {
        ...
    }

    
    
    [AutoInjectsSingleton]
    internal class SingletonClassOnly
    {
        ...
    }

Whilst you can implement multiple attributes of different lifetimes, avoid doing so as it could cause confusion of the lifetime of the service. If a class does have multiple attributes it will be registered in the order of the enum, ServiceLifetime.

  [AutoInjectScoped]
  [AutoInjectsSingleton] // This should be what it is registered as
  [AutoInjectTransient]
  internal class ExampleMultipleServiceClass : IExampleMultipleServiceInterface
  {
      ...
  }

Base attribute with a parameter

You can also use the base class if you prefer that. The benefit of this is you will get compiler issues if you use the attribute multiple times.

  // class with interface implementation
  [AutoInject(ServiceLifetime.Scoped)]
  internal class ScopedTestClass : ScopedTestInterface
  {
      ...
  }

  // class only
  [AutoInject(Lifetime.Scoped)]
  internal class ScopedTestClassOnly
  {
      ...
  }

Avaliable Service lifetimes

This is just from the microsoft enum, ServiceLifetime.

  Transient,
  Scoped,
  Singleton
