Compiler Error C3253

'function' : error with explicit override

Remarks

An explicit override was specified incorrectly. For example, you cannot specify an implementation for an override that you also specify as pure. For more information, see Explicit Overrides.

Example

The following example generates C3253:

// C3253.cpp
// compile with: /clr
public interface struct I {
   void a();
   void b();
   void c();
};

public ref struct R : I {
   virtual void a() = 0, I::a {}   // C3253
   virtual void b() = I::a {}   // OK
   virtual void c() = 0;   // OK
};
