v2.0.2 - Windows Content Margin Fix

Release Notes v2.0.2

🐛 Windows Content Margin Fix

Type: Bugfix

This release fixes a critical layout issue on Windows (WinUI) where MAUI margin properties were not being applied to content views within the Shadows handler.

🐛 Issue

In the Windows platform implementation, content views (such as Border or Frame with Margin set) were added directly to the native Grid without their MAUI layout properties being transferred to the platform view. This caused all content to render without spacing, ignoring margin values.

<!-- This margin was being ignored on Windows -->
<sho:Shadows CornerRadius="10">
    <Border Margin="10" Background="White">
        <Label Text="Content" />
    </Border>
</sho:Shadows>

✅ Fix

The Windows ShadowsHandler now explicitly transfers the MAUI content's Margin property to the native WinUI FrameworkElement:

// Manually apply MAUI margin to the platform view
var contentMargin = shadowsView.Content.Margin;
_contentPlatformView.Margin = new Thickness(
    contentMargin.Left,
    contentMargin.Top,
    contentMargin.Right,
    contentMargin.Bottom);

This ensures proper spacing and layout behavior consistent with other platforms.

📝 Technical Details

• Modified: Maui.Shadows/Platforms/Windows/ShadowsHandler.cs
• Added explicit margin transfer from MAUI view to WinUI platform view
• No changes to other platforms (Android, iOS, MacCatalyst remain unchanged)

📦 Installation

dotnet add package Sharpnado.Maui.Shadows --version 2.0.2

🔄 Migration from 2.0.1

Simply update the package version. No code changes required. Windows layouts with content margins will now render correctly.
