Visual C++ compiler does not generate non-CLS compliance warning (309813)

SUMMARY

The Visual C++ .NET or Visual C++ 2005 compiler allows the use of the [assembly:CLSCompliant(true)] attribute, but does not generate an error or a warning when the assembly is exposing a class that is a type that is non-Common Language Specification (CLS) compliant. While the compilation does succeed, this could cause a problem when the assembly is used by another compiler that enforces CLS compliance rules. In this version of the Visual C++ .NET or Visual C++ 2005 compiler if you apply the attribute this causes the appropriate metadata to be emitted. However, Visual C++ .NET or Visual C++ 2005 does not currently enforce the CLS compliance rules.

using namespace System;
[assembly: CLSCompliant(true)];
namespace NonCLSCompliant{
public __gc class Class1
  {
	public:
		UInt32 Test(void);//This should give an error or warning as UInt32 is not CLS compliant..
  };
}
