title: Metadata file not found error
body: <p>I am dealing with a really huge work such that we have a solution and there are about 100-120 projects under it. Once I was trying to launch it but it took extra long I had to cancel it. Now a number of dll files under bin folder are lost, and most of those files were created by fellow projects under the solution. 
  Now I cannot rebuild/build.</p>
  
  <p>Till now:
  -have cleaned and tried to rebuild the solutions and project folders(each folder, is directly under solution contains like 5-6 projects) one by one. I also tried rebuilding projects one by one but it took too long and was useless.</p>
  
  <p>-cleaned the solution, restarted visual studio(even the computer itself), but did not worked.</p>
  
  <p>-cleared the Temporary ASP.NET Files under C:\Windows\microsoft\\ TEmp... and failed to relaunch again.</p>
  
  <p>-Also tried to manually add missing references to projects but since there are over 100 projects it is not useful and will not work. </p>
  
  <p>Any help will be appreciated greatly.
  Thank you for your time.</p>
