title: Enabling IntelliSense in Visual Studio 2013 Express for C++ files with irregular extensions (e.g. .tpp)
body: <p>I am implementing a class template in Visual Studio 2013 Express with a header and implementation file. However, my implementation file (which has a .tpp extension) does not have IntelliSense enabled. Is there any way to enable C++ IntelliSense for this file? </p>
