I want to create a Workflow Activity that has no input controls. I've created a simple activity, deployed and GAC'd the .dll, then created an AIC. The activity appears in the activity picker and can be added to a workflow, but can't be saved. I don't
see any errors in the event viewer.
I imagine there is something wrong in my ActivitySettingsPart but before I pick it apart, I just wanted to be sure that this is possible. Has anyone done this before?
