This is a library of useful bits of code I use in multiple projects. Some of it is stuff I've written, other bits are cobbled together from helpful blog posts (with an effort made toward attribution where appropriate).

• Interactivity triggers and gestures for Windows Phone 7
• Some string extension methods for dealing with delimited lists
• ObservableStack - A Stack that implements INotifyCollectionChanged
• LittleWatson - An implementation of the error reporting code described at Andy Pennell's Blog

You can also get the WP7 versions (both 7.0 and 7.1) as a NuGet package

I use this stuff in my own code, so it's probably more-or-less okay. But all use is at your own risk.
