Hi All,
I'm trying to figure out how to call a
WCF service from a windows smart phone. I have a very simple smartphone console app, which does nothing but launch and make 1 call to the
service. The
service simply returns a string. I am able to instantiate the proxy class but when i call the method it throws an exception:
There was no endpoint listening at
http://mypcname/Service1.svc/basic that
could accept the message. This is
often caused by an incorrect address
or SOAP action. See InnerException, if
present, for more details.
The inner exception:
Could not establish connection to
network.
I've tried to follow this tutorial on setting up services with windows mobile.
I've used the NetCFSvcUtil to create the proxy classes. I have the
service running on IIS on my machine and had the Util consume the wsdl from that location. I've created a basic http binding as suggested in the article and i think i've pointed the proxy at the correct uri.
Here some sections of relevant code in case it's helpful to see. If anyone has any suggestions, i'd really appreciate it. I'm not sure what else i can poke at to get this thing to work.
Thanks!
Client, (Program.cs):
using System;
using System.Linq;
using System.Collections.Generic;
using System.Text;
namespace WcfPoC
{
class Program
{
static void Main(string[] args)
{
try
{
Service1Client proxy = new Service1Client();
string test = proxy.GetData(5);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
Console.WriteLine(e.InnerException.Message);
Console.WriteLine(e.StackTrace);
}
}
}
}
