I quite like the drag and drop pluggable programming blocks in scratch ( http://scratch.mit.edu/ )
I'd like to be able to get users to create their own mini scripts using the same kind of technique...
just wondering if anyone knows of anything similar I could utilise in .NET? ideally in WPF.
It's not .NET, but have you looked at Alice? (http://www.alice.org/)
yeah..... alice is quite interesting.... but scratch is like alice but simpler. Targets a younger age group I think.
But the UI would be perfect for simple scripting
Maybe Windows Workflow Foundation is something for you. You can host the designer in your own application. So end-user can change the logic.
