I am developing my first web application using ASP.Net MVC, and I am in a situation where I would like a background service to process status notifications outside of the application, not unlike the reputation/badge system on stackoverflow.
What is the best way to handle something like this? Is it even possible in a shared-hosting environment like Godaddy, which I am using.
I don't need to communicate with the background worker directly, since I will be adding notification records to a database table with a column set to an "unprocessed" state. Then the worker will just scan the table on a regular schedule and processes what is ready.
Thanks for your advice.
Have you tried with quartz.net? I think it may fit your needs.
also take a look at this Simulate a Windows Service using ASP.NET to run scheduled jobs article.
it explains a nice way to schedule operations with no outer dependence.
The idea is to use Cache timeout to control the schedule. I've implemented it successfully on a project which required regular temp file cleaning. This cleaning is a bit heavy so we move this clean operation in a scheduled job (using the asp.net cache) to avoid having to deploy scheduled task or custom program.
To answer whether GoDaddy will support a seperate service you need to ask them.
However there are a number of creative ways that you can "get around" this issue on shared hosting.
- Have a secure page that's purpose is to execute your background work. You could have scheduled task on a machine under your control that calls to this web page at set intervals.
- Use a variation of the Background Worker Thread answer from @safi. Your background worker thread could check to see if another is already processing and stop, so that only one instance is running at a time.
If only one background task is enough for you then use the WebBackgrounder And this is the article with detailed explanation.
