OData Provider for XPO – Client Side

In the previous posts, we have looked at how the WCF Data Service Provider for XPO works and how to expose existing XPO objects as OData. Now let’s take a look at how to consume them.

First, create a service proxy. Let’s use a public OData feed from the DevExpress Channel.

The wizard will generate proxy client side data objects from the OData metadata.

public class Statistics : INotifyPropertyChanged {
    public Guid Oid { get; set; }
    public int CompletedCount { get; set; }
    public int Count { get; set; }
public class Video : INotifyPropertyChanged {
    public DateTime Date { get; set; }
    public string Description { get; set; }
    public bool Enabled { get; set; }
    public string Location { get; set; }
    public Guid Oid { get; set; }
    public Statistics Statistics { get; set; }
    public string Title { get; set; }
with these we can now make requests like so:

DataContext context 
    = new DataContext(new Uri(""));
foreach(var video in context.Video) {

It is possible to use Dev Express FilterControl on client side to filter the WCF Data Services data?
