mvvm

Notify Property Weaver

I’ve found MVVM to require somewhat excessive amounts of boilerplate code, and as far as I’m concerned if you have a lot of boilerplate (aka. repeated) code then you’re doing it wrong. There’s a few articles out there on using a little IL weaving to automatically provide notifications for the INotifyPropertyChanged interface. This dramatically reduces the amount of boilerplate you have to write, and dramatically increases readability. Simon Cropp has released the best solution by far – a NuGet package that you can integrate into your app and forget about.

The solution works with Silverlight 3.5 and .NET 3.5 onwards. Most importantly it works well with Windows Phone 7 – something many other solutions don’t always work particularly well with. The solution even works automatically with dependencies – so if one property changes as a result of another changing, the notifications will automatically be fired for both properties. Very, very clever.

Go give it a go!
