Wandering through the Wilderness

I just put the latest version of the MVVM helpers online - mvvmhelpers.zip

There's a bunch of new stuff in it - check the release notes for the highlights. There's a set of breaking changes in it as well, specifically I've moved several of the attached behaviors into the new Blend model. Originally in my local version I did it to the JulMar.Wpf.Helpers.dll and got a dependency against System.Windows.Interactivity.dll.

I decided that for this release I didn't want to force that dependency so I created a secondary assembly JulMar.Wpf.Behaviors.dll which has all those behaviors in it. The breaking change is I removed the original attached behaviors from the library (DoubleClickBehavior, NumericTextBehavior, MouseDragBehavior) in favor of using these new versions. I did update the sample to show how they get used.

In a recent Essential WPF class, one of the students wanted an ObservableDictionary which we whipped up there - I cleaned up that implementation somewhat and added it into this library along with some unit tests for it.

Again, please check the readme included in the .zip file -- as always you are free to do whatever you like with this code. If you do anything interesting or fun, let me know!

Thanks for the great set of helpers. Man MVVM rules and you just made it that much easier to implement, especially with the ObservableDictionary. I love it - thanks for making development life a little easier.

Thanks for these great helpers.
I am writing an example WPF application in my company and want to have a mimimal MVVM helper in it. But I am integrating more and more of your excellent work... Guess I should jump in and take it as is.

I've added a property 'IsInDesignMode' to the base VM class, set by the ViewModelCreatorExtension. It allows me to conditionnally do some stuff (like DB access) if the form is in the design window. I can show the code here, but I guess you already have it in your head.
