title: Error while building asp.net mvc website
body: <p>I have been battling this for days and I cant seem to figure out what is the problem...
  I have an Asp.NET mvc 4 web site which works perfect but when I try to deploy it to azure I get this error:</p>
  
  <pre><code>Error   2   The "exists" function only accepts a scalar value, but its 
  argument "$(PackageSourceManifest)" evaluates to "D:\Software 
  Projects\xxx\xxx\xxxWebSite\obj\Debug\Package\xxxWebSite.SourceManifest.xml
  ;D:\Software Projects\xxx\xxx\xxxWebSite\obj\Debug\Package\xxxWebSite.
  SourceManifest.xml" which is not a scalar value.    
  </code></pre>
  
  <p>This happens also whe I try to clean and rebuilt, So  i guess its not the azure deployment process giving me trouble. I have no idea how to handle this and this website is supposed to go live tomorow :(</p>
