Overview

.NET UI development across Blazor, MAUI, Uno Platform, WPF, WinUI 3, and WinForms. This skill covers framework selection, component architecture, XAML patterns, MVVM, platform-specific deployment, accessibility, and localization. Each framework area has a dedicated companion file with deep guidance.

Routing Table

Path resolution: The Companion File column lists filenames relative to this skill's directory. Use Glob to locate the file (pattern: ), then pass the returned absolute path to the Read tool. Do NOT use bare relative paths — the Read tool resolves them relative to the user's project directory, not this skill's location.
