Hello @John Granatino ,
Welcome to Microsoft Q&A forum.
If this issue only appears on .NET based projects, instead of .NET Framework based projects(you can try to create new projects for testing), then you can try to close VS > search and open Edit the system environment variables
> click Environment Variables > in System variables select Path > click Edit > check, if C:\Program Files\dotnet\
and C:\Program Files (x86)\dotnet\
both exist, make sure that C:\Program Files\dotnet\
locate higher than C:\Program Files (x86)\dotnet\
. Also check if you have set any global.json file.
If this issue appears on every projects(.NET Framework and .NET based projects), please check following:
- If you are using any extension/antivirus, try to stop/disable them temporarily and restart VS.
- Try to run VS as administrator.
- Did you change anything before this issue appeared like updating something, modifying some files and installing some programs?
Sincerely,
Tianyu
