title: Visual Studio not showing all Projects in solution
body: <p>I'm not sure why, but Visual Studio is not showing all the projects in my solution.  I need them to show so I can set as default project under solution explorer.  I'm not seeing a fix for this issue in a general internet search.  The closest I see is <a href="https://stackoverflow.com/questions/26912433/visual-studio-solution-explorer-not-showing-files-and-folders">VS not showing files folders</a>, but this is different than my issue.  Hopefully there is an easy way to fix it, without adding things again piecemeal.  My co-workers can see their complete set of projects in solution explorer so it must be a corruption in my workspace.</p>
