title: Package Manager Console Enable-Migrations CommandNotFoundException only in a specific VS project
body: <p>I tried to run the command 'Enable-Migrations' in a new project and I got the message:</p>
  
  <pre><code>PM&gt; Enable-Migrations
  The term 'Enable-Migrations' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verif
  y that the path is correct and try again.

  + Enable-Migrations &lt;&lt;&lt;&lt; 
      + CategoryInfo          : ObjectNotFound: (Enable-Migrations:String) [], CommandNotFoundException
      + FullyQualifiedErrorId : CommandNotFoundException
  </code></pre>
  
  <p>But in all other projects the command runs just fine.</p>
  
  <p>Why is this happening?</p>
  
  <p>BTW, I'm using VS2010 Professional SP1</p>
  
  <p><strong>EDIT:</strong> I reinstalled with the commmand: <strong>Install-Package EntityFramework -IncludePrerelease</strong>
  and the problem went away.</p>
