Need suggestion to improve my programming skill

I am here to discuss what are the possible improvement can be made in order to make the following code covering all the principles of programming paradigm ( SOLID , DRY ...etc ). Basically, I am practicing Design Patterns.

Public interface IProduct
{ 
   Int name {get;set;}
  Product GetProduct();
}

Public class productA:IProduct
{
  productA(string pn)
{

this.name=pn;
}
public int name{get;set;}
Public Product GetProduct()
 { ......}

  }

 Public class productB:IProduct
{
  productB(string pn)
 {
    this.name=pn;
 }

 public int name{get;set;}

 Public Product GetProduct()
   { ......}

 }


 Public interface IProductManager
 { 
  ProductA PrepareProductA(string productName);

  ProductB PrepareProductB(string productName);

 }




 Public class ProductManager: IProductManager
 {
  ProductA PrepareProductA(string productName)
      {
         return new ProductA(productName);
       }

  ProductB PrepareProductB(string productName)
      {
         return new ProductB (productName);
       }
}

IoC using AutoFac

 var container = new Container();
 Container.RegisterType<ProductManager>().As<IProductManager> ().InstancePerhttpRequest();

Controller:

  Public HomeComtroller:    Controller
    {

      Private IProductManager _productManager;
      Public HomeController( IProductManager productManager)
       {
          this._productManager= productManager;
       }

     Public ViewResult GetProductA()
       {   
          var model = _productManager.PrepareProductA( "webapplication");
          return view(model);
       }

       Public ViewResult GetProductB()
       {
        var model = _productManager.PrepareProductB( "MOBILE");
        return view(model);
       }
  }

Many thanks.
