title: VS 2013 MVC 4.5 broken references
body: <p>I have a MVC 4.5 C# project in Visual Studio 2013. It was running perfectly without any errors, until a co-worker started to work with me.</p>
  
  <p>My co-worker's VS version was 2015, and when he synced (via TFS) with my project looks like all my references got broken. Now VS doesn't recognize my Razor tags anymore, and gives me tons of errors and warnings.</p>
  
  <p>Depending on the number of files I open the list of errors and warning get bigger. Here is an example of what it looks like when I open just the main view of the project:</p>
  
  <pre><code>Warning 101 Found conflicts between different versions of the same dependent assembly that could not be resolved.  These reference conflicts are listed in the build log when log verbosity is set to detailed.
