title: Entity Framework 4.1, can't find Load() method?
body: <p>Ok, I'm about to smash my keyboard with a hammer over this.  I decided to play with EF this weekend and I started a project in 4.0.  I find out 4.1 is out so I download and install the package.</p>
  
  <p>Imagine my surprise when I go to use the Load() method in the dbExtensions and it can't find it.  So I add a reference to the EntityFramework binary that the installer created, remove the System.Data.Entity reference from the project, rebuild, and it says</p>
  
  <blockquote>
    <p>"The type
    'System.Data.Objects.ObjectContext' is
    defined in an assembly that is not
    referenced. You must add a reference
    to assembly 'System.Data.Entity,
    Version=4.0.0.0, Culture=neutral,
    PublicKeyToken=b77a5c561934e089'."</p>
  </blockquote>
  
  <p>I tried to regenerate my model, I tried removing things, I tried directly referencing the 4.1 via usings.  Nothing works.</p>
  
  <p>I'm obviously missing something basic.  How in the heck do I tell visual studio to use the 4.1 framework??!!</p>
