Visual Studio 2012 - Intellisense sometimes disappearing / broken

Question

My colleagues and I are using VS2012 for some weeks now. Sometimes after working several hours the intellisense is broken. After closing all open tabs it works again.

Are there more people out there having the same problem? It can't be an extension problem because I have the same problem at home. Maybe there is a workaround for this?

Answer 1

These are the few top solutions for getting Visual Studio 2012 intellisense back on track try them one by one, hope one of them will solve the problem:

When the problem occurs next time follow these: start from #1 and Move to next when the earlier one doesn't work for you

1: Close all the tabs and open your file again. (Thanks to russds)

2: Clean the Build > Close the Solution > Restart Visual Studio > Open the Solution again

3: Goto: Edit > IntelliSense > Refresh Local Cache

4: Close Visual Studio 2012 and delete this folder: %AppData%\Microsoft\VisualStudio\11.0\ReflectedSchemas

5: Goto: TOOLS > Import and Export Settings > Reset all settings

6: Delete .suo file in the project folder. (Thanks to Jason Steele)

I am hopeful your problem will get solved by any of the above six steps. But if it doesn’t after all this than I think you should consider reinstalling your VS2012.

Answer 2

I use Visual Studio 2012 and I have the same problem. To fix it (when Intellisense is not working anymore), I just have to close the current tab (in which Intellisense is not working) and reopen it. There is no need to close Visual Studio or all the tabs.
