Release Notes

This release contains a fix to an issue when used together with MVVM Light Toolkit reported by Loongzxl at http://appbarutils.codeplex.com/discussions/274048.

MVVM Light Toolkit takes advantage of ViewModelLocator which will initialize view models as its static properties. This could cause the original ChangeIsEnabled method got called before OnAttached method. Therefore, app bar items are always enabled in the beginning no matter what value is returned from CanExecute method of a command object.

This fix places the call to ChangeIsEnabled method inside OnAttached method right after the app bar item is found instead of the original OnCommandChanged method.

If you're using MVVM Light Toolkit, make sure you have this fix. Thanks.
