问题
I have recently upgraded to Visual Studio 2017 version 15.6.3. After doing so (and fixing a bunch of other issues), I can no longer open or create .shproj files.
My existing projects say (load failed) next to each shared project file, and I have the following in my output window whenever I try reloading the project:
C:\File\Path\Project.Shared.shproj : error : Expected 1 export(s) with contract name "Microsoft.VisualStudio.ProjectSystem.VS.Implementation.Package.ProjectFactory+ProjectLoadHelper" but found 0 after applying applicable constraints.
Similarly if I try to create a new shared project, I get the same message in a popup:
Microsoft Visual Studio Expected 1 export(s) with contract name Microsoft.VisualStudio.ProjectSystem.VS.Implementation.Package.ProjectFactory+ProjectLoadHelper" but found 0 after applying applicable constraints.
Why is Visual Studio not allowing me to load or create .shproj files and how can I solve it?

I deleted the entire folder at UserName\AppData\Local\Microsoft\VisualStudio (idea from https://developercommunity.visualstudio.com/content/problem/190581/1560-preview-3-breaks-azure-functions-projects.html) and now my .sproj files load.
