Example code for adding to Recent Tasks

I would like to track action progress using the Recent Tasks view.   I can't seem to find any sample code to help.   I saw some other threads that suggested looking at the WSSDK, but I didn't find anything there either.


I see there are objects such as TaskManager and TaskInfo, but I can't figure out how to createTask properly.  Also, it looks like I would need to register my custom task, and I don't know how to do that either.


Suggestions?
