function' : error with explicit override
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.
The following sample 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
};
