WCF Duplex Messaging Help

[Saiyed Alam]

Hello friends I need to broadcast message using WCF service(duplex) and work on that message by listening from clients and also lock that message so that no other client can work on that message or can ask for that to the service. It should be kind of WCF duplex messaging. Can any one tell me how can I do this or any sample of this kind of work or any kind of help would be appreciated. Thanking in Advance Johnny

Just an idea... Perhaps you can broadcast you event with a UDP WCF server or something (just an idea, no clue how feasible it is), here is some WCF UDP explanation: http://msdn.microsoft.com/en-us/magazine/cc163648.aspx[^] Once someone got this event it can call a WCF service to says it handle it! And the WCF service will returns yes or no according to whether it already has a handler. Of course this method should implement some lock mechanism with Mutex
