Compiler Error C2774

'identifier' : no 'put' method is associated with this property

A data member declared with property has no put function, but an expression tries to set its value.

The following sample generates C2774:

// C2774.cpp  
struct A {  
   __declspec(property(get=GetProp)) int prop;  
   int GetProp(void);  

   __declspec(property(get=GetProp2, put=PutProp2)) int prop2;  
   int GetProp2(void);  
   void PutProp2(int);  

int main() {  
   A* pa = new A;  
   int val = 0;  
   pa->prop = val;   // C2774  
   pa->prop++;   // C2774
