title: Azure automatic build failed
body: <p>I have recently created project on visualstudio.com, and enabled continuous build on azure. I created web api project, and created some models and api controllers. Then I deployed it online and it was cool for a good while. Then I updated all dependencies through NuGet. Build went fine on local and also app worked on my local machine. Then I checked in to tfs, and automatic deploying kicked in, with build error. 
  It says: </p>
  
  <p><code>C:\a\src\HitchStopApi\packages\Microsoft.Bcl.Build.1.0.6\tools\Microsoft.Bcl.Build.targets (74): The "EnsureBindingRedirects" task could not be loaded from the assembly C:\a\src\HitchStopApi\packages\Microsoft.Bcl.Build.1.0.6\tools\Microsoft.Bcl.Build.Tasks.dll. Could not load file or assembly 'file:///C:\a\src\HitchStopApi\packages\Microsoft.Bcl.Build.1.0.6\tools\Microsoft.Bcl.Build.Tasks.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the &lt;UsingTask&gt; declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.</code></p>
  
  <p>On my local machine build I get warning for Tests project</p>
  
  <p><code>D:\Programming\Projects\HitchStop\HitchStopApi\packages\Microsoft.Bcl.Build.1.0.6\tools\Microsoft.Bcl.Build.targets(220,5): warning : Project must install nuget package Microsoft.Bcl.</code></p>
  
  <p>On local I use .NET 4.5, MVC4, Entity framework 5.0...</p>
