WPF on .NET 8+: Host builder and dependency injection, MVVM with CommunityToolkit.Mvvm source generators, hardware-accelerated rendering improvements, modern C# patterns (records, primary constructors, pattern matching), Fluent theme (.NET 9+), system theme detection, and what changed from .NET Framework WPF.
Version assumptions: .NET 8.0+ baseline (current LTS). TFM net8.0-windows. .NET 9 features (Fluent theme) explicitly marked.
Scope boundary: This skill owns WPF on modern .NET patterns: Host builder, MVVM Toolkit, performance, modern C#, theming. Migration from .NET Framework to .NET 8+ is owned by [skill:dotnet-wpf-migration]. Desktop testing is owned by [skill:dotnet-ui-testing-core].
Out of scope: WPF .NET Framework patterns (legacy) -- this skill covers .NET 8+ only. Migration guidance -- see [skill:dotnet-wpf-migration]. Desktop testing -- see [skill:dotnet-ui-testing-core]. General Native AOT patterns -- see [skill:dotnet-native-aot]. UI framework selection -- see [skill:dotnet-ui-chooser].
Cross-references: [skill:dotnet-ui-testing-core] for desktop testing, [skill:dotnet-winui] for WinUI 3 patterns, [skill:dotnet-wpf-migration] for migration guidance, [skill:dotnet-native-aot] for general AOT, [skill:dotnet-ui-chooser] for framework selection, [skill:dotnet-accessibility] for accessibility patterns (AutomationProperties, AutomationPeer, UI Automation).
.NET 8+ Differences
WPF on .NET 8+ is a significant modernization from .NET Framework WPF. The project format, DI pattern, language features, and runtime behavior have all changed.
