i am building workflow into Cuyahoga because i really need it..
a few libraries are around:
netBPM (http://www.netbpm.org/)
Castle.Scheduling (http://using.castleproject.org/display/Contrib/Castle.Components.Scheduling-Tutorial)
Castle.Workflow. (http://using.castleproject.org/display/Contrib/Castle.Facilities.WorkflowIntegration)
I am investigating the netBpm one for now because it is designed to work on Mono, and its has everything in a very abstract but well written structure.
Its also really great to open a large code base see that its based on Castle, Rails and NHibernate and imediatly understand its structure. Its makes it just so easy.
The current code base is running off old NHibernate and Castle lib versions and so am going through upgrading it.
Has anyone else done any work in this area of bringing workflow to Cuyahoga ?? I knwo the trunk has some scaffolding for it, but no code yet.
i have to say it is pretty hard to choose which one to use.
WWF is easy, but no mono support, although the Mono Project does have code but its not in the supported base. Its in Olive.
if your doing it hard your probably doing it the wrong way....

Hey Ged,
Did you decide on a route? Not that i'm working on it myself, but i'm interested in it's progress.

jBland - Yes i saw it too.
d3 - But in the end we actually went with a custom solution for now.
The intent is to use the Castle Scheduling facility when it s working with Quartz.net
But for now a primitive solution was good.
The other thing you have to be careful fo is IIS recycling. It kills the event scheduling i believe.
So you have to ping the web site to keep IIS from Recycling.
A simple provisioning server can do this for an web sites as long as you can control the load balancer to make sure you hit the actual web servers you need.
d3. i also saw your post about MVC from MS. I agree its very promising, and i have so had enough of screwing around with asp.net model.
i also am interested in using JQuery with ASp.NET. The main motivation here is to remove the dependency on all the MS bloat client side.
Then i would layer in Comet style and you would have a decent architecture you could really do stuff with.
Its a pity this has not all been integrated. MS you suck in this regards !! Wake UP..

Hey Ged,
I like your ideas, they seem very much inline with my way of thinking.
Can I ask what you did for your primitive solution?
Many thanks
Matt

d3,
all i did was build a job execution engine, and i code each job.
the main thing is concurrency on jobs in a web farm. the jobs are kept in the db as a queue.
then a compute node grabs a job and proceses it. All rety and failure logic is written for each job.
scheduling is not needed for me yet
