This release contains many breaking changes, but some great improvements in the core of the toolkit:

• Multiple behaviors attached to one UIElement
• Behavior attached on non-named UIElement
• Support of Silverlight NameScopes
• Compacted version now works as expected

This is still not fully stabalized, but there should be no more such big breaking changes in future versions.

Feel free to use it, modify it, send feedback, and communicate on it :)

To rebuild Silverlight Behavior Toolkit, you must use Script# 0.4.5.0 or later (http://projects.nikhilk.net/Projects/ScriptSharp.aspx)

Here is a non-exhaustive list of breaking changes:

• SilverlightControlToolkit namespace has become SBT
• Rebranding issue
• Improve scripts size (both for SBT library and client code)
• Behaviors attaching
• ElementName has become read only accessor
• When creating a behavior, the developper must now give the UIElement itself instead of the element name
