Can not consume TFS Event from WCF Service

Question

Hello,

I have a WCF service designed to receive an event from the TFS 2008 server, any time any change occurs.  I have tested that I am able to connect to the WCF Serivce end point from the TFS machine, via WcfTestClient.exe (the TFS server and WCF Services are on different machines).

I have registered for consuming TFS events, with the following command (run on the TFS server):

BisSubscribe.exe /eventType WorkItemChangedEvent /address http://10.43.200.226:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/mex /server TFS /deliveryType Soap

(I did NO other modifications on the TFS server).

I then have the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

using System.Xml.Schema;
using System.Xml.Serialization;

namespace WcfServiceForTFS
{
    // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in App.config.
    [ServiceContract(Namespace = "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Notification/03")]
    public interface ITFSEventSubscriber
    {
        //[XmlSerializerFormat()]
        [OperationContract(Action = "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Notification/03/Notify")]
        [XmlSerializerFormat(Style = OperationFormatStyle.Document)]
        void Notify(String eventXml, String tfsIdentityXml, SubscriptionInfo SubscriptionInfo);

    }

    [Serializable]
    [XmlRoot(ElementName = "SubscriptionInfo", IsNullable= false)]
    [XmlType(TypeName= "SubscriptionInfo")]
    [DataContract(Namespace="http://scheams.microsoft.com/TeamFoundation/2005/06/Services/Notification/03")]
    public class SubscriptionInfo
    {
        public SubscriptionInfo()
        {
        }

        private int _ID;

        [XmlElement(ElementName = "ID", IsNullable = false, DataType = "int")]
        public int ID
        {
            get { return _ID; }
            set { _ID = value; }
        }

        private string _classification;

        [XmlElement(ElementName = "Classification", IsNullable = true, DataType = "string")]
        public string Classification
        {
            get { return _classification; }
            set { _classification = value; }
        }

        private string _subscriber;

        [XmlElement(ElementName = "Subscriber", IsNullable = true, DataType = "string")]
        public string Subscriber
        {
            get { return _subscriber; }
            set { _subscriber = value; }
        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace WcfServiceForTFS
{
    // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in App.config.
    public class TFSEventSubscriber : ITFSEventSubscriber
    {

        public void Notify(String eventXml, String tfsIdentityXml, SubscriptionInfo SubscriptionInfo)
        {
            System.IO.File.WriteAllText(@"C:\tmp\tfsxml.xml", "HIT!: " + eventXml);
        }
    }
}

          <!-- To avoid disclosing metadata information,

Anyone have any suggestions on what is wrong?

Thank you.

Hi AnilCa,

Thanks for your post and it's my pleasure to work with you again.

The error message indicates that message is not in the correct format. It can be caused by incorrect binding. The correct binding is basicHttpBinding. 

Please have a try of the following address to subscribe the event:

BisSubscribe.exe /eventType WorkItemChangedEvent /address http://10.43.200.226:8731/Design_Time_Addresses/WcfServiceLibrary1/Service1/ /server TFS /deliveryType Soap 

Please let me know if it works. Thanks.
