I'm releasing drops frequently for my XamlPad clone, and will continue to do so... ClickOnce deployment makes this pretty simple. New features I added:

• Simple refactoring - specifcally "surround with" for a couple tags
• Snippet support - added a couple common XAML fragments
• Formatting - run the XAML through XmlTextWriter's formatting engine
• Editting arbitrary files - pass a xaml file in on the command line and it will edit that file instead of the default file

I won't be releasing source for a bit, I'm going to play around with binary deployment for a while. A lot of these features are super hacky right now, and I'd like to move to a more data driven model before I release the source (also it's a bit of a hassle to package up the source and everything else... anyone know of a MSBuild extension for including the source in a package?).

Anyway, if you install via the .deploy that I've linked to, these updates will appear automatically sometime between 1 hour and 1 day after I release the build. You can manually force a refresh by clicking on the link again.
