I have a new laptop. After installed Visual Studio 2022, the Source Control Explorer worked. But after I continue to install more other software and deleted some downloaded solution files from TFS, the explorer is stuck in working. It eventually leads to a frozen Visual Studio with busy message.
Using another laptop with Visual Studio 2022 works.
How to debug and fix this issue?
I think your best bet right now would be to uninstall Visual Studio and start from scratch. Depending on what "downloaded solution files" you deleted, something could be seriously messed up with your current installation of VS.
I would do a full re-install and try again. This may end up saving you time versus troubleshooting.
I've been using Visual Studio 2017 15.7 Preview 2 since it was released -- and Preview 1 prior to that. My experience has been pretty good with it.
All of a sudden today, I just can't get into my project any more. When I click the solution open, I get the "Preparing Solution" message and it just hangs there.
If I try clicking anything in Visual Studio, I get the following message but it doesn't really solve anything.
Anyone else is having this issue? Any idea how to fix it? I just can't work on my project because of this issue.
P.S. I've been using the preview version because I wanted to work in ASP.NET Core 2.1 which requires the preview version of Visual Studio 2017.
Found the answer here. In my case, deleting the .vs folder fixed the issue.

I have Visual Studio 2013 which included "PreEmptive Dotfuscator and Analytics".
It's always worked fine for me until recently.
Suddenly it will not open from Visual Studio, icon or commandline.
Even when I manually open it, it does not show up in the task manager.
It simply does nothing.
There's nothing in the Event Viewer logs.
Visual Studio shows no error.
Basically, I can't even begin to find the problem.
I tried to find a download to attempt to reinstall it but all I've seen on the website for this version is that it's included in VS2013.
There's other sites in search results which claim to have the installer but none I trust.
Has anyone had this issue in the past?
It's Visual Studio 2013 Professional on Windows 8.1.
I'm not sure how to address this so I would greatly appreciate any possible input.
Thanks in advance!
You can try uninstalling, wiping the settings, and reinstalling. Dotfuscator Community Edition is uninstallable via the Windows control panel. Once uninstalled, delete %LOCALAPPDATA%\PreEmptive Solutions. You may be able to reinstall it as a component via the Visual Studio installer. If not, it is actually a standalone installer, so if you have a Visual Studio disc or .iso, it will be in \packages\Dotfuscator.
Some time ago I started developing with Visual Studio 2013 Professional and everything worked well. But a few weeks ago I upgraded to the Ultimate version. But since then Visual Studio crashes when I load a project. VS just starts up normally, I can see the menu and log in and stuff like that. But when I open a project it crashes everytime. I tried to repair it VS in the control panel, but still the same problem... Then I reinstalled it but when loading a solution it crashed again. Now I downgraded to Professional again, but now even Professional crashes.
I have been searching on google for a long time to solve this problem. I tried to reconfigure the debugger, even reinstalled it, but no effect. A lot of forums say you have to delete the .suo file in the project, but even that doesn't work...
Is there a solution for this?
UPDATE
When Visual Studio crashes I get this error: https://i.imgur.com/VtaikJ5.png?1
My ActivityLog.xml is on OneDrive: https://onedrive.live.com/redir?resid=B3519F287A9CD3FC!2830&authkey=!AIUDHo1bCZan4Fk&ithint=file%2cxml
I already received the answer from the MSDN forum. And it was caused by the Web Essentials extension tool. And apparently with the Visual Studio Update 4 everything seems to be fixed. The extension tool was causing the error, and that error is fixed in the update.
Thanks for the support everyone!
This morning I faced a problem while opening my Visual Studio solution, and when I tried to run it, it said:
No exports were found that match the constraint contract name
How can I fix this problem?
I solved this problem by clearing Visual Studio Component Model Cache.
Just delete or rename this folder:
%LocalAppData%\Microsoft\VisualStudio\11.0\ComponentModelCache
or
%LocalAppData%\Microsoft\VPDExpress\11.0\ComponentModelCache
and restart Visual Studio.
The version of Visual Studio you have is specified by the number e.g.
Visual Studio 2012 is 11.0 (as shown above)
Visual Studio 2013 is 12.0
Visual Studio 2015 is 14.0
Visual Studio 2017 is 15.0
Visual Studio 2019 is 16.0
For those that don't know:
%LocalAppData%\ is the same as C:\Users\{yourUsername}\AppData\Local
For those who have multiple versions of Visual Studio installed, e.g. 2012 and 2013, it might help to remove the ComponentModelCache for both versions before restarting Visual Studio, e.g. 11.0 and 12.0.
No need to rename or delete the whole folder:
(%AppData%\..\Local\Microsoft\VisualStudio\11.0\ComponentModelCache)
Just rename or delete the Microsoft.VisualStudio.Default.cache file inside the above location.
Visual Studio Express 2012 has different paths.
Visual Studio Express
...\Users\{user}\AppData\Local\Microsoft\WDExpress\11.0\ComponentModelCache
With Visual Studio Express 2012 for Web
...\Users\{user}\AppData\Local\Microsoft\VWDExpress\11.0\ComponentModelCache
I did not have to re-install Visual Studio Express
This will really work like a champ:
Solution: Try to delete ComponentModelCache folder from the below location.
[C:]\Users\[your user name]\AppData\Local\Microsoft\VisualStudio\[Visual Studio version number]
And after successful delete, recreate the folder with the same name, "ComponentModelCache".
This issue can be resolved by deleting or clearing all the folders and files from %AppData%\..\Local\Microsoft\VisualStudio\11.0\ComponentModelCache
This actually clears the Visual Studio component model cache.
On Windows 7 machines, the path is different. When you type %appdata% in Run dialog, it opens the folder C:\Users\<username>\AppData\Roaming.
Click the 'up' button to navigate to the parent folder and select the folder 'Local'.
Final path: C:\Users\<username>\AppData\Local\Microsoft\VisualStudio\11.0\ComponentModelCache
Deleting the Component Model Cache did not work for me (well, the relative directory given above did not exist in my machine). Instead, I installed an extension to Visual Studio 2012 Express. Menu Tools → Extensions and Updates... → Online → Choose any and then download. This apparently invalidates the cache causing Visual Studio to rebuild it.
Here's my source.
For Visual Studio 2013 you need to remove that folder from this path:
%AppData%\..\Local\Microsoft\VisualStudio\12.0
for Visual Studio 2012 and later versions, the solution must be deleting the content of the folder ComponentModelCache:
C:\Users\[username]\AppData\Local\Microsoft\WDExpress\11.0\ComponentModelCache
Visual Studio 2013
C:\Users\[username]\AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache
I had the same problem upon launching Visual Studio 2013 Ultimate, and the solutions here didn't work for me. I tried deleting the mentioned folders and starting Visual Studio again, but it didn't work.
However I had other problems too, like Microsoft.visual studio package did not load correctly and also Page '312e8a59-2712-48a1-863e-0ef4e67961fc' not found VS 2012. The latter refers to a message in the Team Explorer window saying "Page 'somenumber' cannot be found".
So I run devenv /setup on the Visual Studio command prompt with administrative rights. It did the job, and everything is fine now.
Remove ComponentModelCache folder content.
%AppData%..\Local\Microsoft\VisualStudio\11.0\ComponentModelCache
Clearing the folders didn't work for me. So I went to 'Programs and Features' and used the change button to startup the Visual Studio 2013 setup.
In the setup I choose the repair function and that fixed the problem for me.
I had the same problem with Visual Studio Express 2013 of Windows 8.1.
Unfortunatly there was no "ComponentModelCache" folder in
%AppData%..\Local\Microsoft\VisualStudio\12.0\ComponentModelCache.
I found the "ComponentModelCache" folder in
..\Users[username]\AppData\Local\Microsoft\WDExpress\12.0
and solved this problem by removing this folder from there.
If you have VS 2013, you have to go to: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0
then rename the ComponentModelCache folder.
I experienced a similar problem after some updates released from Microsoft (part of them where about .NET framework 4.5).
On the Internet I got the following link to the Microsoft knowledge base article:
Update for Microsoft Visual Studio 2012 (KB2781514)
It worked for me.
This happened to me with Visual Studio 2013 Web, after Windows installed several updates. Unfortunately none of the suggestions in this thread helped.
I had to re-run the installer and select the "Repair" option. After that (and a reboot) it was working once again.
In some cases you may have to repair more than one version of Visual Studio. One example is when a Script Task control in VS 2013 opens VS 2012 when you click Edit Script.
Renaming the ComponentModelCache folder worked for me in Visual Studio 2015, but with a slightly different path:
%AppData%\..\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
I have Windows 7 x64 with a second partition on which Windows 8 (preview installed). While working with Microsoft Visual Studio Express 2012 for Windows Phone, I come up with the same problem. But the ComponentModelCache is found here:
C:\Users\Jayaram\AppData\Local\Microsoft\VPDExpress\11.0
I am unable to delete or rename as I get the "access is denied" message when I try to use command prompt:
Administrator: VS2012 X64 CrossToolsCommandPrompt
This issue is because of a MEF cache corruption.
Installing the feedback extension (or installing any extension) will invalidate the cache causing VS to rebuild it.
click for source.
i experienced this problem in Microsoft Visual Studio Express 2012 for windows phone while trying to open file.
Then i browsed to
C:\Users\MyUserName\AppData\Local\Microsoft\VPDExpress\11.0\ComponentModelCache
And Inside ComponentModelCache i deleted Microsoft.VisualStudio.Default.cache CACHE file. Finaly i restarted visual studio and reopened my project.
Then my problem was solved, i was able to open file.
Note: My OS is windows 8. And i installed SDK 8 for developing windows phone app
Thanks
I am using Visual Studio 2012. After installing the Visual Studio 2013 web express, when I want to run or open any project in Visual Studio 2012 it shows me the following error:
"no exports were found that match the constraint contract name".
I also tried the above solution for clearing the ComponentModelCache,
but I did not find the folder. I solves my problem just by: Repair Visual Studio 2012
For the Express versions of the software, the folder you need is in a slightly different place(s): For Express 2012 for Web it is C:\Users\XXXXXXXX\AppData\Local\Microsoft\VWDExpress - not in the Visual Studio folder.
I got an error with the same error message - two years later.
It's a different problem this time though, related to .NET Core dnx things.
I couldn't find an answer on Stack Overflow, but there's a GitHub issue that contains a workaround: https://github.com/aspnet/Home/issues/1455
Below is the most important part of the workaround:
Delete the entire C:\Program Files (x86)\Microsoft Visual Studio
14.0\Common7\IDE\Extensions\Microsoft\Web Tools\DNX directory. (As far as I understand, it belongs to the old version of ASP.NET Core
RC1, which for some reason is still shipped even with Visual Studio 2015 Update-3).
Delete the C:\Users\<user>\AppData\Local\Microsoft\VisualStudio\14.0\devenv.exe.config file.
Run the Developer Command Prompt for Visual Studio 2015 as Administrator, and execute the devenv /setup command. The new devenv.exe.config file is generated. This time there are many assemblies that refer to the
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\DotNet directory.
Run the Visual Studio 2015 and check that it shows the Microsoft .NET Core Tools (Preview 2) 14.1.20624.0 in the Help => About Microsoft Visual Studio menu.
Thanks to olegburov's post on GitHub for figuring this out.
I had to uninstall some external components like Postsharp and Apex and then it worked. I also tried the chosen solution but it gave me more errors.
Deleting the folders haven't worked for me i have go control panel and repaired
Visual Studio Installer Projects extensions for VS 2013.
And it worked for me
I got this error after reinstalling IntelliJ IDEA and ReSharper for C# in Visual Studio 2013.
First, I got an error problem with extensions, and after this I got this error:
"No exports were found that match the constraint contract name”
I simply removed folder ComponentModelCache and resolved this error.
My 2 cents:
Following all above lifesaving tips, I had a slightly different experience; mine is VS 2017 Community Edition, installed once, and I notice that have all these 3 folders:
%LocalAppData%\Microsoft\VisualStudio\15.0 ==> Empty
%LocalAppData%\Microsoft\VisualStudio\7f0c75b0 ==> has only the CoreCon folder
This is the one that has the ComponentModelCache:
%LocalAppData%\Microsoft\VisualStudio\15.0_7f0c75b0
Deleting only the Microsoft.VisualStudio.Default.cache had no effect.
So, I deleted all 4 files there: .cache, .err, .external and catalogs.
On restarting VS, problem gone and appeared a 5th file:
Microsoft.VisualStudio.Default.scan
Removing ComponentModelCache did not work for me. Reinstalling VS 2019 did thanks to a recommendation on this Microsoft support thread.

This seems to be a known bug with a fix incoming from MS (as of 1/7/2020)
Experienced after upgrading from VS2019 Pro 16.2 (i think it was?) to 16.4.2 using Visual Studio Installer
