c# - Quartz.Net scheduler works locally but not on remote host

Question

I have a timed quartz.net job working fine on my dev machine, but once deployed to a remote server it is not triggering. I believe the job is scheduled ok, because if I postback, it tells me the job already exists (I normally check for postback however). The email code definitely works, as the 'button1_click' event sends emails successfully.

I understand I have full or medium trust on the remove server. My host says they don't apply restrictions that they know of which would affect it. Any other things I need to do to get it running?

}

The scheduler factory should be global to your application. In other words, declare it in Global.asax or similar that effectively gives you a global instance to operate with. You should start the scheduler in your application start if running ASP.NET.

Beware thought. ASP.NET recycles its processes which effective causes shutdown of scheduler (no jobs will run) until next next request comes in to web server to start the scheduler again. The recommended way is to have a windows service for running Quartz.NET jobs.
