You can only use interfaces or object composition where you can simulate inheritance behaviors, e.g.: public sealed class A { public void Method() { } } public sealed class B { In a Class Library (Windows Store apps) project, this would compile fine and be usable from other like-assemblies. namespace WinRTCompNet { public class Person : IPerson { protected string display = string.Empty; private string name = string.Empty; private string surname = string.Empty; public Person() { } public Person(string name, But this is not enough.
