Laurent Bugnion

Nationality: Swiss

Laurent is a highly respected developer and architect in the .NET UX community, probably most famous for creating the MVVM Light Toolkit. MVVM Light has been widely used in WPF, Silverlight, and Xamarin.Forms projects to implement the Model-View-ViewModel pattern, and its influence carries into MAUI (for example, some of its patterns are mirrored in newer MVVM libraries).

Originally from Switzerland, Laurent was a Microsoft Regional Director and MVP for many years before joining first Microsoft and now AWS as a Cloud Developer Advocate. His journey crosses much of XAML’s history – from early WPF to modern .NET MAUI. Laurent has written books and given countless talks; he also actively contributes to open-source (his libraries and samples). Now at AWS, he helps ensure .NET (including MAUI) runs great on Amazon’s cloud.

Laurent’s decades of experience, tool-building (MVVM Light), and advocacy make him a towering figure in this space and one of the top MAUI-related developers.
