A meet a strange problem at compimation saying that a class does not implement an interface.

Lets say a v got a class:

public Class MyClass
{
...
}

And an interace:

public Interface IMyInterface
{
 MyClass PropertyOfMyClass {get;}
}

and now a generic class:

public class MyGeneric<T> where T:MyClass
{
  T PropertyOfMyClass 
  {
    get{return ...;}
  }
}

Until here everythings fine and compiles right.

But this will break at compilation time:

public class MyGeneric<T>:IMyInterace where T:MyClass
    {
      T PropertyOfMyClass 
      {
        get{return ...;}
      }
    }

Saying that MyGeneric does not implements method of IMyInterface. But obviously it does, not ?
