Question

Suddenly my solution tab stopped working on my Visual Studio 2013. Even it is existing project or brand new project it does not show files and folders in Solution Explorer. (File is attached)

I tried to reset settings, restarted PC but did not work. http://msdn.microsoft.com/en-us/library/ms247075(v=vs.100).aspx

I did not installed any new extensions recently I was working what ever I had for a while.

Is there anything else I can do?

Update;

I am also getting this weird message when I click options Icon:

Check this out: http://www.hjerpbakk.com/blog/2014/7/25/no-content-in-solution-explorer-using-visual-studio-2013

To quote... "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."

Answer 2

Just to get the answer here on the same page as the question: users should install (or uninstall) an extension to Visual Studio as this will force a rebuild of the MEF cache. The linked article suggested installing the Microsoft Visual Studio 2013 Feedback Tool extension, which I did do and it worked, but any extension installed through the Tools, Extensions and Updates menu would probably do the job.

I think the cause of this might have been related to an overzealous anti-virus program, but I can't say for sure.

Answer 3

it worked to click "show all files" in the Solution explorer!
