Whenever I unload and reload a c# project file, i am observing '?' sign on every file of the project in VS2013 Update 5 (Ultimate Version). Even though it does not hurt me in any way as i am able to build the project in normal way, it does not look good. Also, if i close the solution and reopen it, it goes away. However, this takes time to reopen the solution which is very annoying. Has anybody seen this behavior or having some idea to resolve it.
Thanks!!
