dotnet-uno-platform

Uno Platform core development: Extensions ecosystem (Navigation, DI, Configuration, Serialization, Localization, Logging, HTTP, Authentication), MVUX reactive pattern, Toolkit controls, Theme resources (Material/Cupertino/Fluent), Hot Reload, and single-project structure. Covers Uno Platform 5.x+ on .NET 8.0+ baseline.

Scope boundary: This skill owns Uno Platform project structure, Extensions ecosystem configuration, MVUX patterns, Toolkit controls, theming, and Hot Reload. Per-target deployment (WASM, iOS, Android, Desktop, Embedded) is owned by [skill:dotnet-uno-targets]. MCP server integration for live documentation is owned by [skill:dotnet-uno-mcp].

Out of scope: Uno Platform testing (Playwright for WASM, platform-specific tests) -- see [skill:dotnet-uno-testing]. General serialization patterns -- see [skill:dotnet-serialization]. AOT/trimming for WASM -- see [skill:dotnet-aot-wasm]. UI framework selection decision tree -- see [skill:dotnet-ui-chooser].

Cross-references: [skill:dotnet-uno-targets] for per-target deployment, [skill:dotnet-uno-mcp] for MCP integration, [skill:dotnet-uno-testing] for testing patterns, [skill:dotnet-serialization] for serialization depth, [skill:dotnet-aot-wasm] for WASM AOT, [skill:dotnet-ui-chooser] for framework selection, [skill:dotnet-accessibility] for accessibility patterns (AutomationProperties, ARIA mapping on WASM).

Single-Project Structure

Uno Platform 5.x uses a single-project structure with conditional TFMs for multi-targeting. One .csproj targets all platforms via multi-targeting.
