Compiler Warning (level 1) C4490

'override' : incorrect use of override specifier; 'function' does not match a base ref class method

An override specifier was used incorrectly. For example, you do not override an interface function, you implement it.

For more information, see Override Specifiers.

The following sample generates C4490.

// C4490.cpp
// compile with: /clr /c /W1

interface struct IFace {
   void Test();
};

ref struct Class1 : public IFace {
   virtual void Test() override {}   // C4490
   // try the following line instead
   // virtual void Test() {}
};
