operator' : the standard boxing and unboxing conversion operators cannot be redefined

The compiler defines a conversion operator for each managed class to support implicit boxing. This operator cannot be redefined.

For more information, see Implicit Boxing.

// C3638.cpp  
// compile with: /clr  
value struct V {  
   V(){}  
   static operator V^(V);   // C3638  
};  
  
int main() {  
   V myV;  
   V ^ pmyV = myV;   // operator supports implicit boxing  
}
