make-wpf-viewmodel

WPF ViewModel Generator

If $0 is empty, use the AskUserQuestion tool to ask: "Enter the ViewModel name (e.g., Dashboard, Settings)". Do NOT proceed until a valid name is provided. Use the response as the ViewModelName for all subsequent steps.

Generate a $0ViewModel class with optional View, DI registration, and DataTemplate mapping. Follows the wpf-dev-pack composition style: ViewModel First Composition + Stateful ViewModel when using CommunityToolkit.Mvvm (Mappings.xaml + implicit DataTemplate resolves the View from the ViewModel type), or View First Composition + Stateful ViewModel when using Prism 9 (RegisterForNavigation + IRegionManager). ViewModelLocator, code-behind DataContext = new VM(), and inline XAML DataContext are prohibited (see prohibitions.md and docs/TERMINOLOGY.md).

• Replace {Namespace} with the project's root namespace detected from csproj or existing code.
• Replace {ViewModelNamespace} with the ViewModel project's CLR namespace for XAML xmlns declaration.

Usage

# ViewModel + View + DI + DataTemplate mapping (full)
/wpf-dev-pack:make-wpf-viewmodel Dashboard --with-view

# ViewModel + DI only (no View, no mapping)
/wpf-dev-pack:make-wpf-viewmodel Settings

# ViewModel + View without DataTemplate mapping
/wpf-dev-pack:make-wpf-viewmodel Report --with-view --no-mapping

Execution Procedure

Step 1: Parse $0

• $0 is the ViewModel name (without ViewModel suffix — auto-appended)
  • e.g., Dashboard → DashboardViewModel.cs + DashboardView.xaml
• --with-view flag: Generate View XAML + code-behind
• --no-mapping flag: Skip DataTemplate mapping registration

Step 2: Locate Target Projects

Search for solution file and identify projects by naming convention:

Project Suffix	Purpose	Files Placed
.ViewModels	ViewModel project	$0ViewModel.cs
.WpfApp	WPF Application	Views/$0View.xaml, DI registration
.WpfServices	WPF Services	(referenced for DI)
