T         


        

Answer 1

I'm afraid that answer is not necessarily correct. In my Windows 8.1 + Visual Studio 2013 for Web (12.0.30723.00 Update 3), there was no ComponentModelCache folder.

Instead, what I did is ran all updates for VS2013 and then went to Control Panel/Programs and Features and performed a repair. Voila, that worked and I think may be a better overall solution.

Answer 2

Running windows 8.1, VS2013.3 and was able to find the folder. Using the find function in 8.1 did not find the folder, but looking into the %APPDATA% folder I was directed to a Roaming folder. Then by going one level up I did see the local folder in AppData.

The final path where I was able to find the folder was the same as mentioned above. C:\Users\\AppData\Local\Microsoft\VisualStudio\12.0

Renaming the folder did work.

Answer 3

I had this problem,

Now I use Windows 8.1 and VS Express 2013 for web. Renaming the folder didn't help as it didn't change when I re-started VS. Repairing the programme didn't help nor did restarting the computer.

What worked for me was just a basic uninstall & reinstall, sometimes a bit of common sense is needed :)

Answer 4

After a reboot and some more research I found this post from a blog. The error described is not the same error I am seeing, however, it was close enough to warrant a try.

Follow the steps:

1. Close Visual Studio
2. Open the folder: %LocalAppData%\Microsoft\VisualStudio\12.0\ (in C:\users\'%userName%'\AppData\Local\Microsoft\VisualStudio\12.0\)
3. Rename the ComponentModelCache folder
4. Restart Visual Studio.

Visual studio will recreate the folder and all will be well with the world (or at least VS). I love a simple solution, and I hope its of use to anybody else who runs into this issue!

Answer 5

Installing Web Essentials 2013 for VS 2013 as suggested here Project does not load after installing visual studio 2013 update 2 in Sagar S.'s solution, worked for me with VS 2013 Update 4.
