Compiler Error C3195

'operator' : is reserved and cannot be used as a member of a ref class or value type. CLR or WinRT operators must be defined using the 'operator' keyword

The compiler detected an operator definition using the Managed Extensions for C++ syntax. You must use the C++ syntax for operators.

The following sample generates C3195 and shows how to fix it:

// C3195.cpp
// compile with: /clr /LD
#using <mscorlib.dll>
value struct V {
   static V op_Addition(V v, int i);   // C3195
   static V operator +(V v, char c);   // OK for new C++ syntax
};
