No EditorOptionDefinition Export Found Error
C#Visual Studio-2013C# Problem Overview
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.
C# Solutions
Solution 1 - C#
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\(inC:\users\'%userName%'\AppData\Local\Microsoft\VisualStudio\12.0\) - 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!
Solution 2 - C#

Solution 3 - C#
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<myUsername>\AppData\Local\Microsoft\VisualStudio\12.0
Renaming the folder did work.
Solution 4 - C#
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.
Solution 5 - C#
Yes I had this same problem with VS2013 and WIndows 7. Renamed folder
> C:\Users\YourUsername\AppData\Local\Microsoft\VisualStudio\12.0
Solution 6 - C#
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.
Solution 7 - C#
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 :)
Solution 8 - C#
Turning off a plugin called "Visual Assist" solved it for me.
