title: .NET project not building after changing the platform to x64 and back to Any CPU
body: <p>I have 5 projects in my .net c# solution. I have changed each of the projects platform to x64 in Build's platform target (This was initially 'Any CPU') and the project worked fine. </p>
  
  <p>Then I changed the platform in solution properties using configuration manager in solution properties (Right Click on Solution -> Properties)</p>
  
  <p>Then I changed then back to Any CPU. But I can not build the solution. There are many errors saying that dlls of each project can not be found.</p>
  
  <p>One thing I noticed when I changed the platform in solution properties and built the built has changed from bin/debug to bin/x64/debug (I am running in debug mode)</p>
  
  <p>Ex error :</p>
  
  <pre><code>Metadata file '[project path]\bin\Debug\Thahavuru.DataAccessLayer.dll' could not be found   
  </code></pre>
  
  <p>I am confused of what has to build the project successfully back again. Help is greatly appreciated. </p>
