title: The type or namespace name 'TeamFoundation' does not exist in the namespace 'Microsoft'
body: <p>I added the following reference to my ASP.NET MVC 4 application using .net 4.0.</p>
  
  <p>I also included the namespace in my Application , but still I see the following error :</p>
  
  <pre><code> Reference : Microsoft.TeamFoundation.Client.dll
  C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Client.dll
  
     "The type or namespace name 'TeamFoundation' does not exist in the namespace 'Microsoft' "
  </code></pre>
  
  <p>I have another console application and I didnt see this error while using the reference in that application . Is there something different I need to do for a Web/MVC application ?
     Please let me know .</p>
  
  <p>There is also this warning I see :</p>
  
  <pre><code>Warning 1   The primary reference "Microsoft.TeamFoundation.Client, Version=12.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL" could not be resolved because it was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".
