Self hosting WCF inside WPF

Question

Hello,

I need to self host a WCF service inside WPF gui. I'm using ServiceHost.

But I still can't solve the problem.

First I host a service:

ServiceHost host;
Service.ISORClient service = new Service.SORClient();
//The next are in window constructor
host = new ServiceHost(service);
host.Open();

And i want to refresh data when I press button, so:

dataGrid1.ItemsSource = service.GetPatients();

It works, but only once. If I try to refresh it more than one time, it just doesn't work.

Here's my WCF service declaration:

    [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]
    public class SORClient : ISORClient
    ... and all the methods come here...

Weird thing is, that when I connect from a client app. I can get all the data, and everything is correct. I just can't get the data into GUI (well, I can get it only one time).

Thank you very much in advance!

Putting aside questions of design, I suspect you've been bitten by the Equals() override issue.

Try this to prove it:

dataGrid1.ItemsSource = null;
dataGrid1.ItemsSource = service.GetPatients();
