I love talking about MVVM and encourage developers working with XAML platforms to at least explore it, learn more about it, and consider using it in whatever way works best for them and their team. I also love the simplicity of MVVM Light and how it's really easy to learn it and start using it quickly. I delivered a session at Microsoft Advanced Technology Days 10 event in Zagreb, Croatia, last week, and here's my presentation.
The session includes some really basic info about MVVM as a pattern. Then I moved on to MVVM Light trying to cover as much as I could. The toolkit is simple, but has a lot of smart things in it, so it was important to cherry-pick the features I thought were the most useful. In the end, I showed a simple demo of using MVVM Light in a Universal app.
I hope you'll like the presentation and find it useful!
