WPF and .NET Desktop Development
Hands-on knowledge for building Windows desktop applications with WPF and .NET, in two forms: technical articles that work through real implementation problems, and open-source apps, libraries, and tools built along the way. It is written for developers who want practical implementation references rather than surface-level overviews.
About This Site
The technical articles cover WPF, XAML, C# and .NET topics in depth — each one states its prerequisites and target environment, explains the cause behind a behavior rather than only the fix, and notes the trade-offs against the alternatives. The applications are the practical counterpart: WPF sample apps, libraries, and tools, published as open source with links to their GitHub repositories.
