Make Wpf Viewmodel

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:

Fallback: If no .ViewModels project exists, place ViewModel in ViewModels/ folder of main WPF project.

Step 3: Generate ViewModel

Create $0ViewModel.cs:

using CommunityToolkit.Mvvm.ComponentModel;
using CommunityToolkit.Mvvm.Input;

namespace {Namespace}.ViewModels;

public sealed partial class $0ViewModel : ObservableObject
{
    [ObservableProperty] private string _title = "$0";

    [RelayCommand]
    private void Loaded()
    {
        // TODO: Initialize data
        // TODO: 데이터 초기화
    }
}

Step 4: Generate View (if --with-view)

Create Views/$0View.xaml:

<UserControl x:Class="{Namespace}.Views.$0View"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:vm="{ViewModelNamespace}"
             mc:Ignorable="d"
             d:DataContext="{d:DesignInstance vm:$0ViewModel}"
             d:DesignHeight="450" d:DesignWidth="800">
    <Grid>
        <TextBlock Text="{Binding Title}"
                   HorizontalAlignment="Center"
                   VerticalAlignment="Center"
                   FontSize="24" />
    </Grid>
</UserControl>

Create Views/$0View.xaml.cs:

namespace {Namespace}.Views;

public partial class $0View
{
    public $0View()
    {
        InitializeComponent();
    }
}

Step 5: Register in DI Container

Locate App.xaml.cs and add registration inside ConfigureServices:

// In ConfigureServices method
services.AddSingleton<$0ViewModel>();

If --with-view:

services.AddSingleton<$0ViewModel>();
services.AddSingleton<$0View>();

Step 6: Add DataTemplate Mapping (unless --no-mapping)

Locate Mappings.xaml (or ViewModelMappings.xaml) and add:

<DataTemplate DataType="{x:Type vm:$0ViewModel}">
    <views:$0View />
</DataTemplate>

If Mappings.xaml does not exist, create it and merge into App.xaml:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Mappings.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

Step 7: Report Results

Output list of generated/modified files and next steps guidance.

Generated File Structure

{ViewModelsProject}/
└── $0ViewModel.cs

{WpfAppProject}/
├── Views/
│   ├── $0View.xaml           (if --with-view)
│   └── $0View.xaml.cs        (if --with-view)
├── Mappings.xaml                  (modified or created)
└── App.xaml.cs                    (DI registration added)

Error Handling

• Missing ViewModel name → output usage instructions
• No WPF project found → suggest ``make-wpf-project` first
• Duplicate ViewModel → warn and abort
• Missing Mappings.xaml → create with App.xaml merge
