Hi there,
 
I am trying theDevForce EF and WPF. The ListBox Control of WPF needs to bind to a collection.  Does DevFoce EF help me to generate the collections? For example, I have table called OrderType and want to show everything in that table, the DevForce EF will generate OrderType class for me, but I can't bind it to the Listbox since it is not a collection. Do I have to get the collection on my own? Is any simple way to do it? Any WPF example with DevForce EF would be helpful.
 
Thanks in advance!

A LINQ query against a DevForce EF EntityManager can be passed directly into the constructor of pretty much any list type.  Generally speaking, you should use a .NET ObservableCollection<T> if you going to do WPF data binding against the list:

   ObservableCollection<Employee> emps = new ObservableCollection < Employee >(_mgr.Employees);

If you're going to do Winform data binding, use a DevForce IdeaBlade.Util.BindableList<T>:
 
   BindableList<Employee> emps = new BindableList< Employee >(_mgr.Employees);
 
For non-data-binding uses, you can use the lighter-weight List<T>
 
   List<Employee> emps = new List< Employee >(_mgr.Employees);
