title: Can I use Extension Methods to implement an Interface?
body: <p>I would like a class to implement an interface, I do not want to change the original class (that would add undesired dependecies).</p>
  
  <p>I know I could inherit from the class and make it's child implement these methods, but then I am faced with a problem how to convert the parent class (that come from the data / ORM) to this presentation class.</p>
  
  <p>If I implement all the interface required methods, will it count as being that interface or not ? </p>
