title: Can't Install Entity Framework via NuGet
body: <p>I am in a new ASP.NET MVC 4 project and I want to make use of Entity Framework v5.</p>
  
  <p>So I opened up my package installer console in Visual Studio 2013 RC and I typed in the following:</p>
  
  <blockquote>
    <p>Install-Package EntityFramework -Version 5.0.0</p>
  </blockquote>
  
  <p>But I get an error! Here is what I get:</p>
