Visual Studio 2022 Issue

I got the following error when I tried to open a web solution in Visual Studio 2022:

"The operation could not be complete value does not fall within the expected range"

Solution

Just solved it. I deleted the .suo files found in the solution main directory and that seems to have fixed it. I would have thought that doing the reset all did this but apparently not but seems like it became corrupted somehow.

Other Solution Suggestion

• Exit Visual Studio
• Click Start
• Type cmd, right-click Command Prompt, and select Run as administrator
• Navigate to the appropriate Visual Studio folder
  VS2012: pushd %programfiles(x86)%\Microsoft Visual Studio 12.0\Common7\IDE
  VS2015: pushd %programfiles(x86)%\Microsoft Visual Studio 14.0\Common7\IDE
  VS2017: pushd %programfiles(x86)%\Microsoft Visual Studio\2017\<Edition>\Common7\IDE
  VS2019: pushd %programfiles(x86)%\Microsoft Visual Studio\2019\<Edition>\Common7\IDE
• Type devenv /setup and press enter
• When the command prompt returns, you're done. Close the command window, reopen Visual Studio, and test to see if the error's resolved.

See more information at Setup (devenv.exe) - Visual Studio 2015 | Microsoft Docs

Issue

In Visual Studio 2022, I got the error message "Predefined type 'type' is not defined or imported".

Solution

To solve the issue I deleted the ".vs" hidden folder. This folder was in the same location of ".sln" file.
