Subscribing to TFS events and WCF - wcf

Question

Sorry for asking a question about something I don't know much about, but I've been pulling my hair out trying to get this working.
So, I have a WCF service that is hosted on IIS and seems to be working insomuch that I can "see" it on the network by going to http://servername/MyService.svc in a browser.
That .svc looks like:
<% #ServiceHost Service="Foo.Bar" %>
The relevant code looks like:
[ServiceContract(Namespace = "http://schemas.microsoft.com/TeamFoundation/2005/06Services/Notification/03")]
public interface IBar
{
[OperationContract(Action = "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Notification/03/Notify", ReplyAction = "*")]
[XmlSerializerFormat(Style = OperationFormatStyle.Document)]
void Notify(string eventXml, string tfsIdentityXml);
}
and:
public class Bar : IBar
{
public void Notify(string eventXml, string tfsIdentityXml)
{
// Just some test output to see if it worked
var path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "tfs.txt");
File.WriteAllText(path, tfsIdentityXml + eventXml);
}
}
That's all been built and the ensuing .dll put into the bin dir in the site root in IIS.
I now want to subscribe via bissubscribe.exe (or a similar method) to TFS check-in events. I tried doing something like:
bissubscribe /eventType CheckinEvent
/address http://servername/MyService.svc
/deliveryType Soap
/server mytfsserver
But nothing; it doesn't even look like there was log activity. So keeping in mind I know nothing about WCF, what am I doing wrong? I imagine the address param is one thing; am I not supposed to point it to the .svc?

I have created a blog post how you can use WCF in combination with the Event Services of TFS: http://www.ewaldhofman.nl/post/2010/08/02/How-to-use-WCF-to-subscribe-to-the-TFS-2010-Event-Service-rolling-up-hours.aspx

TFS 2010 and WCF 4.0 configurations are described below...
Method signature:
public void Notify(string eventXml) /* No SubscriptionInfo! */
Web config:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="Microsoft.TeamFoundation, Version=10.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>
</assemblies>
</compilation>
</system.web>
<system.serviceModel>
<services>
<service behaviorConfiguration="NotificationServiceBehavior" name="TF.CheckinListener.CheckinListener">
<endpoint address="Notify" binding="wsHttpBinding" bindingConfiguration="noSecurity" contract="TF.CheckinListener.ICheckinListener" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="NotificationServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
</binding>
<wsHttpBinding>
<binding name="noSecurity" maxBufferPoolSize="20000000" maxReceivedMessageSize="200000000">
<readerQuotas maxStringContentLength="200000000" maxArrayLength="200000000" />
<security mode="None" />
</bindings>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Subscription address for bissubscribe:
http://MachineName/VirtualDirectoryName/Service.svc/Notify

One point that jumps out is the fact you have a method that doesn't return anything except void. Those should be marked as "one-way" method in WCF:
[ServiceContract(Namespace = "http://schemas.microsoft.com/TeamFoundation/2005/06Services/Notification/03")]
public interface IBar
{
[OperationContract(Action = "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Notification/03/Notify", ReplyAction = "*", IsOneWay=true)]
[XmlSerializerFormat(Style = OperationFormatStyle.Document)]
void Notify(string eventXml, string tfsIdentityXml);
}
Add the "IsOneWay=true" to your [OperationContract] attribute.
Other than that, there's nothing obviously wrong in your code, but to really tell, we'd need a lot more config info to really tell. Try the IsOneWay=true first and see if that solves your issue.

How is your service configured? In particular, is it configured to use basicHttpBinding?
Try creating a client to call your service to make sure it can be called.
Then, see if there's an example service from the TFS SDK - see if you can get the example to work.

I was able to complete this connection with the following:
[ServiceContract(Namespace = "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Notification/03")]
public interface ITeamSystemObserver : IObservable
{
[OperationContract( Action = "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Notification/03/Notify", ReplyAction = "*" )]
[XmlSerializerFormat(Style=OperationFormatStyle.Document)]
void Notify(string eventXml, string tfsIdentityXml, SubscriptionInfo SubscriptionInfo);
}
Note you are missing the SubscriptionInfo parameter. Here is my web.config:
<basicHttpBinding>
<binding name="TfsEventServiceBasic">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Ntlm" />
</security>
</binding>
</basicHttpBinding>
