Problem with using Event driven webservice from Windows app

Question

Hi All,

 

Currently, I have been facing an issue with using an event-driven web service.

 

Here's my scenario: I have a windows app running on 150+ user machines. Basically, this app subscribes to an event from a WCF service in order to receive some updates. Windows client saves these updates into Local DB.

 

Here's How I subscribe to the event from my client: 

 

Webservice object = new Webservice("Endpoint");

object.eventhandler += new eventhandler(Targetmethod);

 

So, the Targetmethod will be invoked when the event occurs. 

 

 

Problem: When the WCF service goes down for a while and back to live, our targetmethod in the client is not being called, as a result, we not receiving any updates.

 

Now how can I handle this situation in my client and continue receiving updates once the service is back and running?

 

Any advice will be highly appreciated  

 

Thanks,
Srini
