So my question is. Where to find the installers for Roslyn Project Templates for VS 2015?
I believe you're looking for the .Net Compiler Platform SDK: https://visualstudiogallery.msdn.microsoft.com/2ddb7240-5249-4c8c-969e-5d05823bcb89
You may also need to install the Visual Studio 2015 SDK: https://msdn.microsoft.com/en-us/library/bb166441(v=vs.140).aspx
You can also download the .Net Compiler Platform SDK from within Visual Studio:
