Entity Framework 6.x from 4.x DbExtensions is not declared. It maybe inaccessible due to its protection level.

After upgrade from Entity Framework 4.x to 6.x get various errors:
Error
DbExtensions.Load(context.myItems)
myBindingSource.DataSource = DbExtensions.ToBindingList(context.myItems)
Solution
context.myItems.Load()
me.myDataGridView.DataSource = context.myItems.Local.ToBindingList
End.
