Compiler Error C3653

'function' : cannot be used as a named override: a function being overridden not found; did you forget to name the function explicitly, using a :: operator?

An explicit override specified a function that was not found in any interface. For more information, see Explicit Overrides.

The following sample generates C3653:

// C3653.cpp
// compile with: /clr
public interface struct I {
   void h();
};

public ref struct X : public I {
   virtual void f() new sealed = J {};   // C3653 no J in scope
   virtual void g() {}   // OK
   virtual void h() new sealed = I::h {};   // OK
};
