title: Microsoft.Threading.Tasks not found, .net 4.0
body: <p>I converted my .net application to .net 4.0 and because im using async/await I installed NuGet packages Async for .Net 4 and dependencies Microsoft BCL...</p>
  
  <p>When I build my application, everything goes well but when I move my app .exe to correct environment I get the error:</p>
  
  <blockquote>
    <p>System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Threading.Tasks, Version=1.0.12.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a or one of its dependencies. </p>
  </blockquote>
  
  <p>If I include Microsoft.Threading.Tasks.dll to my applicatin directory everything works well (this .dll is copied to my app build directory).</p>
  
  <p>So the question is do I need to include this Microsoft.Threading.Tasks.dll to my app installer or Is there way to bundle this to my app .exe?</p>
