Why do I get an error when I compile a C++ file with a line using namespace System?

I have the CC++ file that works perfectly on Microsoft Visual. Trying to run and complile it Matlab and got many errors. The attached lines i.e using namespace System; using namespace System::Runtime::InteropServices;

Gave out the following errors D:\Semproj\USB\protocol.cpp(13) : error C2871: 'System' : a namespace with this name does not exist

D:\Semproj\USB\protocol.cpp(14) : error C2653: 'System' : is not a class or namespace name

Are you using a "C++ MEX file" in MATLAB or are you directly trying to use the C++ file from Microsoft Visual?

If you are using "C++ MEX file", then can you paste the verbose output of the mex command?

>>mex -v mexfilename
