WPF Behavior Generator

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

Generate a $0Behavior class based on Microsoft.Xaml.Behaviors.Wpf.

• Replace {TargetType} with the appropriate WPF type (e.g., TextBox, UIElement, Window) based on the behavior name and context.
• Replace {Namespace} with the project's root namespace detected from csproj or existing code.
• Replace {Project} with the target project path.

Generated Code

public sealed class $0Behavior : Behavior<{TargetType}>

    public static readonly DependencyProperty IsEnabledProperty =
        DependencyProperty.Register(
            nameof(IsEnabled),
            typeof(bool),
            typeof($0Behavior),
            new PropertyMetadata(true));

    public bool IsEnabled
    {
        get => (bool)GetValue(IsEnabledProperty);
