Need help on Messaging Architecture Using WCF

[Saiyed Alam]

Hello friends I'm working on a ERP system where there are in total 8 modules. Now I need to create a duplex messaging system using WCF through user of one module with communicate with users of other modules. Like user of sales dept will request user of management dept to check on a certain request and give decision. Then the management user may accept that request or not and let the sales user know his feed back at the same time. Is there any sample of this or any help would be appreciated. Thanking in Advance Saiyed ALam

One last thing... Don't generate the proxy and client class for your services, just reuse the same classes on both sides! it will save you a lot of grief! Service interface example

\[ServiceContract(Namespace = "http://agtrix.net/AgDat/XDN")\]
public interface IEventService
{
	\[OperationContract()\]
	Guid SubmitRawEvent(EventData evt);
}

data to be passed around

\[DataContract(Namespace = "http://agtrix.net/AgDat/XDN")\]
public class EventData
{
	\[DataMember()\]
	public string DataSource { get; set; }

	\[DataMember()\]
	public Guid EventGroupId { get; set; }

	\[DataMember()\]
	public List<EventAttribute> Attributes { get; set; }
}

\[DataContract(Namespace = "http://agtrix.net/AgDat/XDN", IsReference = true)\]
public class EventAttribute
{
	\[DataMember()\]
	public string ContextName { get; set; }
	\[DataMember\]
	public string ImportName { get; set; }
	\[DataMember\]
	public string Value { get; set; }
}

Note: the Attribute are critical to the service!
