[RESOLVED] backgroundworker

[arkiboys]

Hi,
There is a fully working .net windows application which uses the background worker process in the form.

Using my new silverlight 4 application, I now would like to make it use the functionalities as the application in the winform i.e. background worker, etc...

Question:
As I am using the wcf to retrieve data and pass to the silverlight page, how/where do I use the background worker process? Do I use it in the service or in the silverlight page?

Alternatively, should I just have a timer in the silverlight page which calls the wcf every second or so to update the silverlight page with data?

Thanks
