No EditorOptionDefinition Export Found Error

Question

In Visual Studio 2013 I started getting the following error when trying to open C# files:

No EditorOptionDefinition export found for the given option name:
Tabs/ConvertTabsToSpaces
Parameter name: optionID

I was having no issues all morning until I closed and re-opened a C# solution I was working on when this error started. I checked and this error happens when I open any C# project on this computer. I also tried opening the same project from my other computer and it works fine, so this is not a project error.

I have not changed any VS settings, and I was just trying to open the package manager when this presented itself.

I am at a loss and Dr. Google is not of much help thus far.

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:

Close Visual Studio
Open the folder: %LocalAppData%\Microsoft\VisualStudio\12.0\ (in C:\users\'%userName%'\AppData\Local\Microsoft\VisualStudio\12.0\)
Rename the ComponentModelCache folder
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!

The easiest part of this answer is to located ComponenetModeCacheFolder. Cheers!! Thank you. – Ishwor Khanal Feb 16 '18 at 11:54
This helped to fix the issue in VS 2017, This should be informed to Visual Studio Team to fix in future releases. – Shaiju T Oct 29 '19 at 15:37

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.

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.

For the guys down voting my answer, may I suggest you leave a comment on why I'm wrong or misguided. I tried to give an explanation that worked fine and didn't require manually deleting a directory. – HiDefLoLife Jan 02 '15 at 23:59

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 :)

Turning off a plugin called "Visual Assist" solved it for me.
