What workflow framework to use in C#
I have to create a workflow in C# capable of moving an object (persisted as a database record) through an approval workflow where people are required to perform some sort of action or validation.
We initially looked at Windows Workflow Foundation but shied away from it because it seemed so infrastructure-heavy (and besides we don't really like Microsoft products). We looked at ObjectFlow because it's lightweight, but I'm having trouble figuring out how to persist & resume workflow states. It almost seems like it's too lightweight.
Does anyone have a particular favorite framework for doing workflow? I'm open to ideas (even to WWF, if you can explain why it's your favorite).
As the question @gsharp linked to says, WF 4 isn't entirely easy to use. However, ObjectFlow has an easy fluent interface that is light and built with solid design principles. Given the apparent lack of decent workflow frameworks, I decided to pitch in and extend ObjectFlow with an IStatefulWorkflow that contains a .Yield() method capable of yielding workflow processing to the calling method so that it's state can be persisted.
The end result of my work will be a new release at codeplex in a couple weeks. Until then, you can follow my progress at github.
Have you looked at Drools.Net?
Drools.NET is a Business Rules Engine (BRE) based on Charles Forgy's Rete algorithm. Developers can now exploit a powerful Rule Engine through a completely managed .NET code base! Drools.NET is based on Jboss Rules, and comes with all the features of that Rules Engine.
