VS2005, C++/CLI
when having multiple "using namespace", only the top level namespace is shown in the member drop downlist.
example:
using namespace System::Collections::Generic;
using namespace System::Data::SqlClient;
using namespace System::Data;
using namespace System::Net;
using namespace System::Text;
using namespace System;
using namespace System::Threading;
using namespace Microsoft;
using namespace Microsoft::CSharp;
this produces 5 times "using namespace System" and 2 "using namespace Microsoft"
