Need help in creating the scheduling service

I need to create a scheduling service which will poll the database after a specific time interval, pick the required objects and send it to a WCF service to perform the required task.

Shall I use the windows worker thread? or is there any other ready to use component that windows / third party provide开发者_JAVA技巧s?

You can use SQL Server Agent for this task.

why don't you create a windows service... and in that run a timer that will fire an even on specific interval... this allows you to run your code at specific interval... without any user interaction..
