I need to build a custom *.vsl library for Visio 2013, using Visual Studio 2013. The C++ sample “CppVsl Starter Project” from the Visio 2013 SDK has instructions for Visual Studio 2010 and Visual Studio 2012, but not for Visual Studio 2013. From within VS 2013, I don’t see “Visio Addon” in the list of project templates. How do I make this happen? Does anyone have another simple *.vsl example?
