Fatal Error C1191

'dll' can only be imported at global scope

The instruction to import mscorlib.dll into a program that uses /clr programming cannot appear in a namespace or function, but must appear at global scope.

The following sample generates C1191:

// C1191.cpp
// compile with: /clr
namespace sample {
   #using <mscorlib.dll>   // C1191 not at global scope
}

Possible resolution:

// C1191b.cpp
// compile with: /clr /c
#using <mscorlib.dll>
namespace sample {}
