      • I have an activity which invokes a web service. The web service has a parameter which isn't serializeable, and is throwing an exception when the SqlPersistance trys to unload the runtime. So my question is, is there some property or setting I can set to make the SqlPersistance ignore certain parts of my workflow, since really they don't need to be persisted anyway

      • Hi folks. Do you guys have any best practices for testing Especially around automated testing As I understand it, since Cardspace uses the secure desktop, and since you can't disable that, the Cardspace UI can't be scripted (good thing) and therefore can't be used in automated testing (bad thing). Do you have any ideas about how to work around this Cheers Matt
