Please add sample for using with web app and windows service.

Please provide some samples with web application and windows service.
The current [one ](http://docs.hangfire.io/en/latest/background-processing/processing-jobs-in-windows-service.html) is very poor and doesn't explain much.
Ex: I have some service Service.SentEmail() and in which way is it possible to add task for this in web app but execute in win service?

Or maybe it is just misunderstanding and we can't use it in the such way?
