VSTO, Outlook add-ins, and Visual Studio 2015

Question

Starting with Visual Studio RC, Visual Studio 2015 appears to no longer support the Office Add-In project types from Visual Studio Tools for Office (VSTO). Lots of googlin

Answer 1

With the help from James Randal we found an answer. We created a brand new empty Sharepoint Add-in then compared a newly created .csproj XML with the OfficeDev PNP .csproj XML.

Deleting the GUID's above does not help as then Visual Studio does not recognize the project as a Sharepoint project.

Answer : Edit the .csproj XML to change 16.0 to be 16.1 worked for me. You will still need to right-click on Sharepoint Project and install missing features but it finishes without the error message now.
