Who it is for

For everyone after K2 who has to build a new program for Windows computers and wants to stay with C# and the Kladde's stack. Maintaining and moving existing WPF or Windows Forms programs is taught by the Modernisierung course.

Prerequisites

K2 (C#, the Kladde's web API with sign-in, tests) or the placement test. A Windows computer is needed.

Afterward, you can

  • Create and start a WinUI 3 project and explain how it is built
  • Build interfaces in XAML with layouts, ListView and NavigationView
  • Build pages with MVVM and dependency injection and test the view models without a window
  • Load data through the web API, sign in and keep a cache
  • Implement window state, single instance and notifications of a Windows program
  • Build and sign an MSIX package and tell the ways of distribution apart
