c# - Why can I not see the property Local when using Entity Framework?

Question

I know I am missing something completely obvious, but why can't I see the property Local when working with an EF context? The typical example online looks like the following:

context.Parents.Local

But I am unable to see the Local property. Now from what I understand, Local is a member of the DbSet class, and I don't think I'm working with a DbSet in my application. What I do know is I've added a reference to the EntityFramework, have using System.Data.Entity and everything else I'm familiar with doing is working just fine. Except Local isn't there, and I really do need some sorting capability for my DataGridView.

Help!

DbContext, DbSet etc. are part Entity Framework 4.1/4.2 which is shipped, among others, as the EntityFramework NuGet package. With just the .NET Framework you only have what is now called "Core EF Runtime" according to this:

In short, you need to install EF 4.1/4.2.
