Generate MVVM Feature

Generates a standard Wpf.Ui View and ViewModel pair for PocketMC and registers them in the Dependency Injection container.

Instructions

1. Verify the argument

   • Ensure the user provided a FeatureName (e.g., ModManagement).
   • Determine if the feature should go into an existing folder (e.g., Features/Marketplace) or a new one based on the context.

2. Create the ViewModel

   • Location: PocketMC.Desktop/Features/<Area>/<FeatureName>ViewModel.cs
   • It must inherit from ObservableObject and implement INavigationAware (if it's a page).
   • Use Constructor Injection for any services.

3. Create the View (Code-behind)

   • Location: PocketMC.Desktop/Features/<Area>/<FeatureName>Page.xaml.cs
   • Inherit from INavigableView<T> where T is the ViewModel.
   • Assign ViewModel property in the constructor.

4. Create the View (XAML)

   • Location: PocketMC.Desktop/Features/<Area>/<FeatureName>Page.xaml
   • Use ui:Page from http://schemas.lepo.co/wpfui/2022/xaml.
   • Set d:DataContext for design-time bindings.

5. Register in DI Container

   • Open PocketMC.Desktop/Composition/ServiceCollectionExtensions.cs or the specific <Area>ServiceCollectionExtensions.cs.
   • Add .AddTransient<<FeatureName>Page>()
   • Add .AddTransient<<FeatureName>ViewModel>()

Examples

• "Generate MVVM for PlayerSettings"
• "Create a new AddonBrowser view and viewmodel"
