I recently upgraded Visual Studio to try to resolve another problem, but now I'm being hit by a new one. When I try to open a .sln file which opened fine in Visual Studio 2017, I get the following error message:
Microsoft Visual Studio
The 'Microsoft.VisualStudio.ProjectSystem.VS.Implementation.SharedProjectFilesPackage.SharedProjectFilesPackage, Microsoft.VisualStudio.ProjectSystem.VS.Implementation, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' package did not load correctly.
The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file 'C:\Users\Victor\AppData\Roaming\Microsoft\VisualStudio\15.0_2f0e30dc\ActivityLog.xml'.
Restarting Visual Studio could help resolve this issue.
Continue to show this error message? Yes No
I have tried deleting the UserName\AppData\Local\Microsoft\VisualStudio
folder, as that seems to have solved other problems:
Visual Studio 2017 cannot create or open .shproj (shared Project) files
That didn't help in this case, though.
How can I solve this problem and load my project again?
Update: Completely uninstalling and re-installing Visual Studio did not solve the problem either.
Update 2: Creating a brand new Xamarin.Forms project also failed.
