Visual Studio 2012 “Show All Files” button missing

Question

In my solution I have three projects: Console application, class library, and a website project. The Show All Files button is visible on the console and class library proje

Answer 1

None of the above answers worked for me. If this is the case for you try right-clicking on any file in your project, then choosing "Show all files". The "Show all files" icon should now appear on this and all subsequent Solution Explorer windows.

YMMV, be kind. :-)
