Question

I am working through the book Learning WCF and on the first tutorial lab HelloIndigo I am receiving the following error.

Could not connect to http://localhost:8000/HelloIndigo/HelloIndigoService. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000.

It appears in the Client project on the line string s = proxy.HelloIndigo();

EndpointAddress ep = new EndpointAddress("http://localhost:8000/HelloIndigo/HelloIndigoService");

IHelloIndigoService proxy = ChannelFactory<IHelloIndigoService>.
            CreateChannel(new BasicHttpBinding(), ep);
string s = proxy.HelloIndigo();
Console.WriteLine(s);
Console.WriteLine("Press <ENTER> to terminate Client");
Console.ReadLine();

I have intensively googled on this but I am none the wiser.

Can anyone explain the issue and how to remedy?

Answer 1

It could be several things, first things to check are:

• Is the service running?
• Is there an endpoint configured a that address?
• Is there any firewall that is blocking the request?

Try puting the endpoint address in a browser and see if you can browse to it.
