Recommend a C# Task Scheduling Library [closed]

I'm looking for a C# library, preferably open source, that will let me schedule tasks with a fair amount of flexibility. Specifically, I should be able to schedule things to run every N units of time as well as "Every weekday at XXXX time" or "Every Monday at XXXX time". More features than that would be nice, but not necessary. This is something I want to use in an Azure WorkerRole, which immediately rules out Windows Scheduled Tasks, "at", "Cron", and any third party app that requires installation and/or a GUI to operate. I'm looking for a library.

Solution 1:

http://quartznet.sourceforge.net/

"Quartz.NET is a port of very propular(sic!) open source Java job scheduling framework, Quartz."

PS: Word to the wise, don't try to just navigate to quartz.net when at work ;-)

Solution 2:

I used Quartz back in my Java days and it worked great. I am now using it for some .Net work and it works even better (of course there are a number of years in there for it to have stabalized). So I certainly second the recommendations for it.

Another interesting thing you should look at, that I have just begun to play with is the new System.Threading.Tasks in .Net 4.0. I've just been using the tasks for parallelizing work and it takes great advantage of multi cores/processors. I noticed that there is a class in there named TaskScheduler, I haven't looked at it in detail, but it has methods like QueueTask, DeQueTask, etc. Might be worth some investigation at least.

Solution 3:

See A New Task Scheduler Class Library for .NET on Codeproject.

Solution 4:

I read about Quartz in this question How might I schedule a C# Windows Service to perform a task daily?. It's a C# library and allows for flexible scheduling.
