SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

System theme detection and runtime switching can be cumbersome across platforms; this Skill provides a centralized API to detect the current OS theme and apply an app-level theme programmatically.

Core Features & Use Cases

  • GetCurrentOsTheme() returns Light or Dark.
  • GetRootTheme(XamlRoot?) and IsRootInDarkMode(XamlRoot?) determine theme state for a root.
  • SetRootTheme(XamlRoot?, bool) and SetApplicationTheme(XamlRoot?, ElementTheme) switch themes at runtime.
  • Use cases: Build theme-aware UI that responds to system theme; toggle dark mode in code; ensure cross-platform consistency.

Quick Start

Detect the current OS theme with GetCurrentOsTheme() and apply SetApplicationTheme(null, ElementTheme.Dark) to switch to dark mode.
