Is there something I can/should do about this VS 2013 exception?

On loading my ASP.NET app/site, I get this err msg: "An exception has been encountered. This may be caused by an extension."

It then says to look in this file:

C:\Users\Clay\AppData\Roaming\Microsoft\VisualStudio\11.0\ActivityLog.xml

...in which I did find three entries that may be related to the problem, yet they are "Greek to me". Due to their voluminosity, I am just including the first one here:

This error is often caused by a corruption in the cached metadata. Why this occurs I do not know, but clearing the cache will usually return Visual Studio to working order:

And then this exception will also occur when you have installed Visual Studio update 1,2,3 or 4 and have other visual studio parts (like the web tools) that were built against an older version. Upgrading them to the latest version usually also helps quite a bit:
