I have tried each of the answers in this thread for fixing the latest release and none helped. I downgraded to Version 17.5.5 and I am finally able to work again.

I reinstalled my machine (keeping files). Quicker than wasting my time trying everything else first. Working now.

I've avoided using VS Pre for months because this issue after an update. I switched back to VS 2019 to finish a project.
I've now updated VS 2022 Pre to 17.7.0-pre.1.0 and still the same issue when I try to open a solution: RoslynPackage' package did not load correctly., -The 'CSharpPackage' package did not load correctly.

I've tried:

deleting the ComponentModelCache.

devenv /resetsettings

devenv /clearcache

devenv /updateconfiguration

Nothing works. I may abandon VS 2022 altogether.

After I had been trying all the fixed in this thread I found thread which fixed it for other versions of VS.
Start "Developer Command Prompt for VS 2022".
Then run the following in the prompt.

devenv.exe /clearcache

devenv.exe /updateconfiguration

This fixed it for me.

:-(

I also did remove the cache folder "%localappdata%\Microsoft\VisualStudio\17_xxxx\ComponentModelCache"

Also did a repair of the VS 2022 ...

So maybe it's a combination of all the above.

Hello @Shanmugavel Manickam ,

Welcome to Microsoft Q&A forum.

Please close Visual Studio, go to C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_XXXXXXXX folder and rename/remove ComponentModelCache folder. Open VS and check again.

Please also try to reset(run devenv /ResetSettings in Developer Command Prompt for Visual Studio 2022 Community) and repair VS(VS Installer > More > Repair).

Feel free to let us know the results.

Update 1:

This issue is fixed in Visual Studio 2022 version 17.6.2, please try to update VS 2022 to the latest version.

See this thread: RoslynPackage fails to initialize due to SettingsEditorFactory dependency error and release note for details.

Sincerely,

Tianyu

Do you have any extensions installed?

Hi @Shanmugavel Manickam ,

Not sure if you are using any extensions, but looks like replacing the net462 build of System.ValueTuple.dll with a net47 build of the assembly in the GAC works for you.

I guess you also post a same thread on our Developer Community, just to double confirm with you if this issue was disappeared? I will help to list the workaround here:

Run following command in an elevated command prompt

gacutil /if "<vsinstalldir>\Common7\IDE\PublicAssemblies\System.ValueTuple.dll"

And delete the %USERPROFILE%\AppData\Local\Microsoft\VisualStudio\17.0_<instanceid>\ComponentModelCache directory.

Feel free to contact us if you get any other issues in the future.

Have a great day.

@Tianyu Sun-MSFT

Thanks this really worked to use gacutil command. It fixed the issue!

PS: I had exactly same issue with 2022 and 2022 preview, in different configurations (tried to repair, re-install, admin modes, cleaning caches and everything else). Also, the WinForms designer just refused to open with different kind of errors, mainly "Exception of type System.Exception was thrown" in a tiny error message box, or this "HRESULT" message.

I have tried deleting the folder below to no avail.

%localappdata%\Microsoft\VisualStudio\17_xxxx\ComponentModelCache

I tried reinstalling VS 2022 also without success.

Temporary solution to get it running was to downgrade my VS 2022 to version 17.5.5.

Similar issue here - https://learn.microsoft.com/en-us/answers/questions/1286664/the-project-system-components-package-did-not-corr

Looks like issues caused by the last update. No answer as of yet

I have the same issue too following the last update (VS 2022 Professional 17.6.0)

Cleared cache
Deleted User folders
Repaired installation
Removed and did a clean install
All extensions disabled and still not working

Concerned I'm going to have to reinstall my machine just to get VS working again
