I just installed Visual Studio 2015 and now want to start a new MonoGame project (C#, Windows DX).
I got MonoGame installed, as well as XNA.
The problem is that the templates are not showing up in the New Project dialogue.
On Visual Studio 2013, they showed up here, they are also nowhere to be found aynwhere else in the Project tree.
So I searched for the templates, they exist in the location where they should be:
C:\Users\<user>\Documents\Visual Studio 2015\Templates\ProjectTemplates\Visual C#\MonoGame
I found out why it wasn't working:
Apparently, the MonoGame installer puts the Templates in the wrong folder for Visual Studio 2015.
The correct folder for VS2015 is
C:\Users\user\Documents\Visual Studio 14\Templates\ProjectTemplates\Visual C#
The MonoGame installer installs to C:\Users\user\Documents\Visual Studio 2015\Templates\ProjectTemplates\Visual C#
So, when the folder MonoGame inside that folder gets moved to the first one, and the
devenv.exe /installvstemplates command gets executed, the templates show up.
