Vista - How to retrieve metadata from self-hosted service

Hello all

<disclaimer>I'm just getting started with WCF, so this is probably just a
dumb newbie question.</disclaimer>

I have a simple service (the usual ICalculator sample) hosted in a console
app. The app starts up OK and is listening on the configured port.
Application config file follows:
<?xml version="1.0" encoding="utf-8" ?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<system.serviceModel>
<services>
<service
name="MathServer.MathServer" >
<endpoint
address="http://localhost:1234/MathServer"
binding="basicHttpBinding"
contract="MathServer.IMath" />
</service>
</services>

</system.serviceModel>
</configuration>


Using IE I am attempting to query the metadata from this service, using a
URL of http://localhost:1234/MathServer?wsdl. However this is returning an
error "500 Internal Server Error". The body of the reply from the service
contains a SOAP envelope containing more information about the error as
follows: "DestinationUnreachable" "The endpoint is unable to process the
message at this time".

I don't understand why my service does not return metadata when requested.
Is this supposed to work for self-hosted services?

I have setup a similar example, hosted using IIS, and this returns wsdl
metadata without problem.

Thanks in advance for any assistance

hello,
You can see wsdl in the ie when wcf is hosted in the self-hosted.Maybe
your service class has some problem

hello,
You need to make sure your service is still running when you want to
get wcf wsdl from ie

Thanks for the reply.

Yes, my service host program (a console app) is running when I try to get
wsdl. Some part of WCF is working, because my service host is accepting the
connection from IE, processing the request and returning a SOAP error reply
(along with HTTP error 500).

If I try to query wsdl when my service host is not running then IE returns
"The page cannot be display", as expected.


The source for my service follows:

using System;
using System.ServiceModel;

namespace MathServer
{
[ServiceContract]
public interface IMath
{
[OperationContract]
int Add( int x, int y );
}

class MathServer : IMath
{
static void Main( string[] args )
{
Console.WriteLine( "Starting" );
ServiceHost sh = new ServiceHost( typeof( MathServer ) );
sh.Open();
Console.WriteLine( "Press enter to terminate" );
Console.ReadLine();
Console.WriteLine( "Stopping service listener" );
sh.Close();
Console.WriteLine( "Stopped" );

}

public int Add( int x, int y )
{
return x + y;
}
}
}

hello,
In Feb CTP,Instance a ServiceHost class,you need pass a uri to let wcf
know where to find WCF metadata information

ServiceHost sh = new ServiceHost(typeof(MathServer),new
Uri("http://localhost:1234/MathServer"));

Thanks, wsdl query working fine now.

I still don't understand why I have to pass a uri to the constructor when
that same uri is in my config file.
