Compiler Error C3800

Error Message

'declaration': cannot mix properties and events

You cannot declare a construct to be both a property and an event.

C3800 is only reachable using /clr:oldSyntax.

The following sample generates C3800:

// C3800.cpp
// compile with: /clr:oldSyntax
#using "mscorlib.dll"

__delegate void MyDel();
public __gc struct S
   __property __event void set_E(MyDel*)
   }   // C3800

int main()
