Question

I am using following code to get all the pages of pages WCF Service:

 var ent = new DataSource(new Uri("http://api.abc.com/Service.svc"));

 ent.Credentials = new NetworkCredential("username", "pass");

DataServiceCollection<Rentals> rentals = new DataServiceCollection<Rentals>(ent.Rentals);
while (rentals.Continuation != null)
{
   rentals.Load(ent.Execute<Rentals>(rentals.Continuation));
}

foreach (var r in rentals)
{
   Response.Write(r.ListingID + "<br />");
}

but I am getting this error:

An attempt to track an entity or complex type failed because the entity or complex type ‘NorthwindService.ServiceReference1.Rentals’
does not implement the INotifyPropertyChanged interface.

Answer 1

I think You might not enable code generation of binding interfaces. This is covered in step 2 of the walk-through as per this link

Go try setting the environment variables as mentioned in step 2 and then right-click your service reference and select “Update Service Reference…”
