I have a VS extension I've been working on that was working fine. When I run it in VS it would open the experimental instance of VS and load just fine. However, between checking it into TFS, some NuGet references got all messed up and in the process of trying to fix that (it now builds), it's now stopped debugging in the VS experimental instance. Hitting F5 just gives me the complaint about
A project with an Output Type of Class Library cannot be started
Does anybody know how to fix this? What in the project or solution settings tells it to start debugging in Visual Studio?
I tried comparing .vsproj files from a completely clean VSIX project, but I'm not seeing it
Ok - never mind, I found it.
Under the project properties on the Debug tab, you need to set Start external program to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\devenv.exe (for example)
And then under Start Options you need to add /rootsuffix Exp to the Command line arguments
I'm not sure how these got lost in the first place, but in case anybody else encounters the same problem.
