I recently installed VS 2022 and opened a project I am working on which has been created and worked ok on VS 2019.

When using VS 2022 and trying to access the properties window of the application I get the following error:

===================

I have tried various thing suggested on other threads where users were unable to access the properties of their solution like:

  • Disable all extensions, restart VS
  • Re-enable all extensions, restart VS
  • Remove %AppData%\Microsoft\VisualStudio folder and restart VS
  • Once the %AppData%\Microsoft\VisualStudio folder got re-created, remove it again and run VS 2022 as administrator
  • Instead of right clicking VS 2022 on my taskbar and clicking the project I want to open, I tried opening it directly from the .sln file
  • Also tried opening VS 2022 and going to File > Open > Project/Solution and finding my project and opening it this way

None of the above have worked.

Do I need to re-create this project in VS 2022 for this to work or does someone have any knowledge of this error and has resolved it in the past and could share their information?
