Entity Framework generated classes are not in the namespace I require, is there a way of changing the namespace it uses without regenerating?

Where should the namespace be provided if a regenerate is required? I am trying to use partial classes from within the Models namespace however they don't match.

The produced entity foundation classes are located in the condensed code segment below.

namespace projectname
{
   #region Contexts

   /// <summary>
  /// No Metadata Documentation available.
  /// </summary>
  public partial class MyClass
  {

  }
}

A class is added to my models folder,

namespace projectname.Models
{

    public partial class MyClass
    {
     //etc, etc 
    }
}

The compiler is seeing both project names, thus as you can see, the namespaces don't match, which causes problems when I try to utilize them. Models. project name and my class. MyClass.

I would like some advice on the correct way to fix this, preferably to update the E.F. classes so they exist in the projectname.Models namespace, but I am not sure how to go about it.
