Just copied this from an internal mail I received. Very cool stuff although the Story Board stuff leaves a lot to the imagination if you want to link it to a holiday scenario.
To get the upper hand playing WoW with your teenage cousins, build an add-on using the new AddOn Studio for World of Warcraft, an open-source development tool that brings the Visual Studio experience to building World of Warcraft add-ons. This WoW development environment is built on the Visual Studio 2008 Shell (isolated mode). Key features include a visual design surface, Lua code editor, FrameXML IntelliSense, and auto-generation of Lua events.
If you’re making a holiday movie of the family and need to draft out the sequence of events, check out the Storyboard Designer, a simple tool for anyone who wants to diagram (model) and generate documentation for a storyboard scenario. The Storyboard Designer provides an example of what can be accomplished by hosting DSL tools in the Visual Studio 2008 Shell (isolated mode). Watch the screencast: StoryboardDesignerDemo.
You can also find on CodePlex a version of IronPython hosted in the Visual Studio Shell: IronPython Studio. If you’re looking for version of IronPython that merges with your installation of Visual Studio (standard or above) complete with IntelliSense, compiler, debugging, etc., download the free Visual Studio SDK. The IronPython Studio is a free, standalone language tool; for more details watch the IronPython Studio screencast video demo.
