Usage

Startup.cs

Go to "ConfigureServices" Make sure that you create the Autofac Container as usual for your Framework (Supported is .NET Standard 2+) like its described here: https://autofac.readthedocs.io/en/latest/integration/index.html

and then you create the instance BEFORE any registration.

   public IServiceProvider ConfigureServices(IServiceCollection services)
   {
          ......
          var builder = new ContainerBuilder().AddEasyPropInject();
          
          //Add your services now as usual 
    }
    

Usage in the Code

using Autofac.EasyPropInject.Annotations;
public class MyClass:IMyInterface 
{ 
    public MyClass(ISomeOtherInterface someService) 
    { 
      
    }
    
    [FromAutofac]
    public IUnitOfWork unit { get;set; }


    [FromAutofac] //Since Autofac.EasyPropInject@1.2.5: Support for protected properties
    protected IMyService serviceProtected {get;set;}

    [FromAutofac] //Since Autofac.EasyPropInject@1.2.5: Support for private properties
    private IMyService2 servicePrivate {get;set;}

    [FromAutofac(typeof(IUnitOfWork))]
    public UnitOfWorkBaseClass unit2 {get;set;}
}

Once IMyInterface is resolved and activated EasyPropInject Middleware will try to resolve the types of unit and unit2. In this case EasyPropInject will try to resolve IUnitOfWork from current container and will try to set and Instance of IUnitOfWork to unit2 and use it as UnitOfWorkBaseClass. Warning Since the type casting feature new in 1.2.x of EasyPropInject is handy sometimes its truly unsafe and you should to be sure what you are doing.
