After installation of visual studio 2017
getting his error for VSIX projects
... any suggestion to resolve the issue?
Severity Code
This error appeared for me randomly without doing any change in the code. It disappeared after removing the following folders:
C:\Users\\AppData\Local\Microsoft\VisualStudio\15.0_765fd02aExp C:\Users\\AppData\Roaming\Microsoft\VisualStudio\15.0_765fd02aExp
After it I am able to build again without error.
To find the folders I recommend to use some file search application and use the string "15.0_Exp*".
