I have a WF service with a custom activity and a custom designer (WPF). I want to add a validation that will check for the presence of some value in the web.config file.

At runtime I can overload void CacheMetadata(ActivityMetadata metadata) and thus I can do the validation happily there using System.Configuration.ConfigurationManager to read the config file.

Since I also want to do this at design time, I was looking for a way to do this in the designer.
