Compiler Error C3457
'attribute': attribute does not support unnamed arguments
Source annotation attributes, unlike CLR custom attribute or compiler attributes, only support named arguments.
Example
The following sample generates C3457.
#include "SourceAnnotations.h"
[vc_attributes::Post( 1 )] int f(); // C3457
[vc_attributes::Post( Valid=vc_attributes::Yes )] int f2(); // OK
