If i try to run 2 clients in the same machine (and the server, naturally), the second client cannot register itsel, and i receive a framework error. Wasn't it supposed to work with as many clients as wished?

Thanks in advance!

Found a workaround:

In the client code:

SyncContext = SynchronizationContext.Current;

InstanceContext instanceContext = new InstanceContext(this);

ServiceProxyInstance = new ServiceProxy(instanceContext);

I added these lines:

WSDualHttpBinding binding = (WSDualHttpBinding)ServiceProxyInstance.Endpoint.Binding;

string clientCallbackAddress = binding.ClientBaseAddress.AbsoluteUri;

clientCallbackAddress += Guid.NewGuid().ToString();

binding.ClientBaseAddress = new Uri(clientCallbackAddress);

And now it works!

What do you think?

Best regards,

Nuno

Use of .vdproj file seems to keep source from opening with VS Express 2008. Any thoughts?

How can I get this project to run on another machine and have the server on another? I am getting an error that says:

"Inconceivable! An error has occurred. The caller was not authenticated by the service"

Help! I have a similar project like your and am running into issues.

Thanks.

@Johny79, contacting the author for advise on this.

@Johny79: This is the response I got:

The project can run across multiple machines, as I tested this before publishing; judging from his comment he appears to have the same issue with a different project as well. There are quite a few permissions/IIS/WCF security issues that may need to be checked within his environment to allow WCF communication to work. if you receive more detail on issue we can think on it. I'd start with making sure a basic web service can be hosted and viewed from another machine, and then run Fiddler to determine if any errors are blocking communication. I would also make sure the port number used is not being blocked along the way.
