title: Found conflicts between different versions of the same dependent assembly that could not be resolved
body: <p>When I clean and then build my solution that has several projects, the output window reports that the build succeeded. However, when I view the <em>Error List Window</em>, it shows me this warning:</p>
  
  <blockquote>
    <p>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.    C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets</p>
  </blockquote>
  
  <p>When I double-click this message, it opens the <em>C:\Program Files (x86)\MSBuild\12.0\bin\Microsoft.Common.CurrentVersion.targets</em> file but I don't understand anything in it.</p>
  
  <p>I am using Visual Studio Express 2013 for the Web.</p>
  
  <p>How do I find out what's wrong and with which DLL and how do I then make the warning go away?</p>
