Can't access most standalone Windows 7 WCF application in non-domain
Trying to run a bootable application on my Win 7 system with little success. The application starts, but I cannot access it from the WCF Test Client or by adding a link in VS. I've read that there seem to be 1000 posts of similar problems, but none of the solutions seem to work.
I did this:
netsh http add urlacl url=http://+:9090/hello user=LocalPC\UserName
And then this:
netsh http add iplisten ipaddress=0.0.0.0:9090
Here's the code for
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
Uri baseAddress = new Uri("http://localhost:9090/hello");
// Create the ServiceHost.
using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))
{
// Enable metadata publishing.
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
host.Description.Behaviors.Add(smb);
// Add MEX endpoint
host.AddServiceEndpoint(
ServiceMetadataBehavior.MexContractName,
MetadataExchangeBindings.CreateMexHttpBinding(),
"mex");
// Add application endpoint
host.AddServiceEndpoint(typeof(IHelloWorldService), new WSHttpBinding(), "");
// Open the ServiceHost to start listening for messages. Since
// no endpoints are explicitly configured, the runtime will create
// one endpoint per base address for each service contract implemented
// by the service.
try
{
host.Open();
}
catch (Exception excep)
{
string s = excep.Message;
}
}
}
When I try to access the WCF test client I get:
Error: Unable to get metadata from http: // localhost: 9090 / hello If this is a Windows (R) Communication Foundation service that you will access, make sure you enable metadata publishing to the specified address. To help publish metadata, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455 .

If a service is defined in the current solution, try building the solution and adding the service reference again.

The problem is that you are letting the ServiceHost go out of scope right away.
The using statement is used for cleanup convenience when that block of code goes out of scope, but you have nothing to prevent it. So essentially you open a connection, but then it is placed almost instantly ... which closes the connection.
As long as you don't run into permission issues, this approach should work for you. That being said, this is just a demo version. In fact, you probably don't want your WCF service to bind directly to your form, but defined at the application level.
public partial class WcfHost : Form
{
private ServiceHost _svcHost;
private Uri _svcAddress = new Uri("http://localhost:9001/hello");
public WcfHost()
{
_svcHost = new ServiceHost(typeof(HelloWorldService), _svcAddress);
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
_svcHost.Description.Behaviors.Add(smb);
InitializeComponent();
FormClosing += WcfHost_FormClosing;
}
private void WcfHost_Load(object sender, EventArgs e)
{
try
{
_svcHost.Open(TimeSpan.FromSeconds(10));
lblStatus.Text = _svcHost.State.ToString();
}
catch(Exception ex)
{
lblStatus.Text = ex.Message;
}
}
void WcfHost_FormClosing(object sender, FormClosingEventArgs e)
{
_svcHost.Close();
lblStatus.Text = _svcHost.State.ToString();
}
}
[ServiceContract]
public interface IHelloWorldService
{
[OperationContract]
string SayHello(string name);
}
public class HelloWorldService : IHelloWorldService
{
public string SayHello(string name)
{
return string.Format("Hello, {0}", name);
}
}
