WebOne way to achieve this is to add a constructor on class B that accepts a parameter of type B, and add data manually. public class B { public B (A a) { this.Foo = a.foo; this.Bar = a.bar; // add some B-specific data here } } I disagree that you should have a Clone () method on A that returns a B, as this introduces a circular dependency. WebAs Grzenio correctly notes, an expression of type T is not convertible to TwoType.
