WPF IValueConverter rules: MarkupExtension singleton, pure functions, null/UnsetValue handling, TemplateBinding.

WPF Freezable performance rules: Freeze() all Brush/Pen/Geometry; create-and-freeze in constructor, reuse in OnRender.

WPF MVVM layer-separation rules: no System.Windows in ViewModels, BCL-only types, CommunityToolkit.Mvvm base classes. Preloaded into MVVM-related wpf-dev-pack agents.

Banned wpf-dev-pack patterns (P-001..P-004): ViewModelLocator, code-behind DataContext, Stateless ViewModel, mixing composition paths.

WPF rendering anti-patterns: no InvalidateVisual in loops, no resource allocation in OnRender.

WPF ResourceDictionary rules: Generic.xaml as MergedDictionaries hub only, per-control style files, resource order.

View-ViewModel wiring for CommunityToolkit.Mvvm: Mappings.xaml + implicit DataTemplate (ViewModel First).

View-ViewModel wiring for Prism 9: RegisterForNavigation + IRegionManager (View First).

WPF UI virtualization for large collections: VirtualizingStackPanel, recycling, pixel scroll.

Releases a new version of the WpfDevPackMcp NuGet MCP server (the server under mcp/), which is versioned independently of the wpf-dev-pack plugin and of knowledge content. Bumps the four version strings that must stay in lockstep (csproj <Version>, the dnx pin in wpf-dev-pack/.mcp.json, and BOTH version fields in mcp/.mcp/server.json), then builds, packs, pushes to NuGet, re-pins after the package goes live, and optionally re-publishes to the Official MCP Registry. Use when code under mcp/ or its packaging changed and must be republished. Do NOT use for knowledge-topic edits (served live, no version bump) or plugin-only changes (use /wpf-dev-pack-release). Usage: /releasing-wpfdevpackmcp [version e.g. 0.1.4]

Executes the wpf-dev-pack release workflow: runs VersionReleaseChecker, commits changes, pushes, creates a GitHub tag and release note. Owner-only release tool. Use when releasing a new version of wpf-dev-pack plugin.
