Safe Area & Edge-to-Edge Layout (.NET 10+)

.NET 10 introduces a brand-new, cross-platform safe area API that replaces the legacy iOS-only UseSafeArea and the layout-level IgnoreSafeArea properties. The new SafeAreaEdges property and SafeAreaRegions flags enum give you per-edge, per-control safe area management on Android, iOS, and Mac Catalyst from a single API surface.

This is new API surface in .NET 10. If the project targets .NET 9 or earlier, these APIs do not exist. Guide the developer to the legacy ios:Page.UseSafeArea and Layout.IgnoreSafeArea properties instead.

When to Use

• Content overlaps status bar, notch, Dynamic Island, or home indicator after upgrading to .NET 10
• Implementing edge-to-edge / immersive layouts (photo viewers, video players, maps)
• Keyboard avoidance for chat or form UIs
• Migrating from ios:Page.UseSafeArea, Layout.IgnoreSafeArea, or WindowSoftInputModeAdjust.Resize
• Blazor Hybrid apps that need CSS env(safe-area-inset-*) coordination
• Mixed layouts with an edge-to-edge header but a safe-area-respecting body

When Not to Use

• Projects targeting .NET 9 or earlier — use the legacy iOS-specific APIs
• General page layout questions unrelated to system bars or keyboard — use standard layout guidance
• App lifecycle or navigation structure — use maui-app-lifecycle or Shell guidance
• Theming or visual styling — use the maui-theming skill

Inputs

• Target framework: must be net10.0-* or later for the new APIs
• Target platforms: Android, iOS, Mac Catalyst (Windows does not have system bar insets)
• UI approach: XAML/C#, Blazor Hybrid, or MauiReactor

SafeAreaRegions Enum

[Flags]
public enum SafeAreaRegions
{
    None      = 0,       // Edge-to-edge — no safe area padding
    SoftInput = 1 << 0,  // Pad to avoid the on-screen keyboard
    Container = 1 << 1,  // Stay inside status bar, notch, home indicator
    Default   = -1,      // Use the platform default for the control type
    All       = 1 << 15  // Respect all safe area insets (most restrictive)
}

SoftInput and Container are combinable flags: SafeAreaRegions.Container | SafeAreaRegions.SoftInput = respect system bars and keyboard.

SafeAreaEdges Struct

public readonly struct SafeAreaEdges
{
    public SafeAreaRegions Left { get; }
    public SafeAreaRegions Top { get; }
    public SafeAreaRegions Right { get; }
    public SafeAreaRegions Bottom { get; }

    // Uniform — same value for all four edges
    public SafeAreaEdges(SafeAreaRegions uniformValue)

    // Horizontal / Vertical
    public SafeAreaEdges(SafeAreaRegions horizontal, SafeAreaRegions vertical)

    // Per-edge
    public SafeAreaEdges(SafeAreaRegions left, SafeAreaRegions top,
                         SafeAreaRegions right, SafeAreaRegions bottom)
}

Static presets: SafeAreaEdges.None, SafeAreaEdges.All, SafeAreaEdges.Default.

XAML Type Converter

Follows Thickness-like comma-separated syntax:

<!-- Uniform -->
SafeAreaEdges="Container"

<!-- Horizontal, Vertical -->
SafeAreaEdges="Container, SoftInput"

<!-- Left, Top, Right, Bottom -->
SafeAreaEdges="Container, Container, Container, SoftInput"

Control Defaults

Control	Default	Notes
ContentPage	None	Edge-to-edge. Breaking change from .NET 9 on Android.
Layout (Grid, StackLayout, etc.)	Container	Respects bars/notch, flows under keyboard
ScrollView	Default	iOS maps to automatic content insets. Only Container and None take effect.
ContentView	None	Inherits parent behavior
Border	None	Inherits parent behavior

Breaking Changes from .NET 9

ContentPage default changed to None

In .NET 9, Android ContentPage behaved like Container. In .NET 10, the default is None on all platforms. If your Android content goes behind the status bar after upgrading:

<!-- .NET 10 default — content extends under status bar -->
<ContentPage>

<!-- Restore .NET 9 Android behavior -->
<ContentPage SafeAreaEdges="Container">

WindowSoftInputModeAdjust.Resize superseded

WindowSoftInputModeAdjust.Resize still exists and still compiles (it is not removed and not obsolete), but it is Android-only. For cross-platform keyboard avoidance prefer SafeAreaEdges="All" (or the SoftInput region) on the ContentPage.

Usage Patterns

Edge-to-edge immersive content

Set None on both page and layout — layouts default to Container:

<ContentPage SafeAreaEdges="None">
    <Grid SafeAreaEdges="None">
        <Image Source="background.jpg" Aspect="AspectFill" />
        <VerticalStackLayout Padding="20" VerticalOptions="End">
            <Label Text="Overlay text" TextColor="White" FontSize="24" />
        </VerticalStackLayout>
    </Grid>
</ContentPage>

Forms and critical content

<ContentPage SafeAreaEdges="All">
    <VerticalStackLayout Padding="20">
        <Label Text="Safe content" FontSize="18" />
        <Entry Placeholder="Enter text" />
        <Button Text="Submit" />
    </VerticalStackLayout>
</ContentPage>

Keyboard-aware chat layout

<ContentPage>
    <Grid RowDefinitions="*,Auto"
          SafeAreaEdges="Container, Container, Container, SoftInput">
        <ScrollView Grid.Row="0">
            <VerticalStackLayout Padding="20" Spacing="10">
                <Label Text="Messages" FontSize="24" />
            </VerticalStackLayout>
        </ScrollView>
        <Border Grid.Row="1" BackgroundColor="LightGray" Padding="20">
            <Grid ColumnDefinitions="*,Auto" Spacing="10">
                <Entry Placeholder="Type a message..." />
                <Button Grid.Column="1" Text="Send" />
            </Grid>
        </Border>
    </Grid>
</ContentPage>

Mixed: edge-to-edge header + safe body + keyboard footer

<ContentPage SafeAreaEdges="None">
    <Grid RowDefinitions="Auto,*,Auto">
        <Grid BackgroundColor="{StaticResource Primary}">
            <Label Text="App Header" TextColor="White" Margin="20,40,20,20" />
        </Grid>
        <ScrollView Grid.Row="1" SafeAreaEdges="Container">
            <!-- Use Container, not All — ScrollView only honors Container and None -->
            <VerticalStackLayout Padding="20">
                <Label Text="Main content" />
            </VerticalStackLayout>
        </ScrollView>
        <Grid Grid.Row="2" SafeAreaEdges="SoftInput"
              BackgroundColor="LightGray" Padding="20">
            <Entry Placeholder="Type a message..." />
        </Grid>
    </Grid>
</ContentPage>

Programmatic (C#)

var page = new ContentPage
{
    SafeAreaEdges = SafeAreaEdges.All
};

var grid = new Grid
{
    SafeAreaEdges = new SafeAreaEdges(
        left: SafeAreaRegions.Container,
        top: SafeAreaRegions.Container,
        right: SafeAreaRegions.Container,
        bottom: SafeAreaRegions.SoftInput)
};

Decision Framework

Scenario	SafeAreaEdges value
Forms, critical inputs	All
Photo viewer, video player, game	None (on page and layout)
Scrollable content with fixed header/footer	Container
Chat/messaging with bottom input bar	Per-edge: Container, Container, Container, SoftInput
Blazor Hybrid app	None on page; CSS env() for insets

Blazor Hybrid Integration

For Blazor Hybrid apps, let CSS handle safe areas to avoid double-padding.

1. Page stays edge-to-edge (default in .NET 10):

<ContentPage SafeAreaEdges="None">
    <BlazorWebView HostPage="wwwroot/index.html">
        <BlazorWebView.RootComponents>
            <RootComponent Selector="#app" ComponentType="{x:Type local:Routes}" />
        </BlazorWebView.RootComponents>
    </BlazorWebView>
</ContentPage>

2. Add viewport-fit=cover in index.html:

<meta name="viewport" content="width=device-width, initial-scale=1.0,
      maximum-scale=1.0, user-scalable=no, viewport-fit=cover" />

3. Use CSS env() functions:

body {
    padding-top: env(safe-area-inset-top);
    padding-bottom: env(safe-area-inset-bottom);
    padding-left: env(safe-area-inset-left);
    padding-right: env(safe-area-inset-right);
}

Available CSS environment variables: env(safe-area-inset-top), env(safe-area-inset-bottom), env(safe-area-inset-left), env(safe-area-inset-right).

Migration from Legacy APIs

Legacy (.NET 9 and earlier)	New (.NET 10+)
ios:Page.UseSafeArea="True"	SafeAreaEdges="Container"
Layout.IgnoreSafeArea="True"	SafeAreaEdges="None"
WindowSoftInputModeAdjust.Resize	SafeAreaEdges="All" on ContentPage

The legacy ios:Page.UseSafeArea and Layout.IgnoreSafeArea properties still compile but are marked obsolete. IgnoreSafeArea="True" maps internally to SafeAreaRegions.None. WindowSoftInputModeAdjust.Resize is not obsolete — it remains supported, but is Android-only.

<!-- .NET 9 (legacy, iOS-only) -->
<ContentPage xmlns:ios="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.iOSSpecific;assembly=Microsoft.Maui.Controls"
             ios:Page.UseSafeArea="True">

<!-- .NET 10+ (cross-platform) -->
<ContentPage SafeAreaEdges="Container">

Platform-Specific Behavior

iOS & Mac Catalyst

• Safe area insets cover: status bar, navigation bar, tab bar, notch/Dynamic Island, home indicator
• SoftInput includes the keyboard when visible
• Insets update automatically on rotation and UI visibility changes
• ScrollView with Default maps to UIScrollViewContentInsetAdjustmentBehavior.Automatic

Transparent navigation bar for content behind the nav bar:

<Shell Shell.BackgroundColor="#80000000" Shell.NavBarHasShadow="False" />

Android

• Safe area insets cover: system bars (status/navigation) and display cutouts
• SoftInput includes the soft keyboard
• MAUI uses WindowInsetsCompat and WindowInsetsAnimationCompat internally
• Behavior varies by Android version and OEM edge-to-edge settings

Common Pitfalls

1. Forgetting to set None on the layout too. ContentPage SafeAreaEdges="None" makes the page edge-to-edge, but child layouts default to Container and still pad inward. Set None on both page and layout for truly immersive content.

2. Using SoftInput directly on ScrollView. ScrollView manages its own content insets and ignores SoftInput. Wrap the ScrollView in a Grid or StackLayout and apply SoftInput there.

3. Confusing Default with None. Default means "platform default for this control type" — on ScrollView (iOS) this enables automatic content insets. None means "no safe area padding at all."

4. Double-padding in Blazor Hybrid. Setting SafeAreaEdges="Container" on the page and using CSS env(safe-area-inset-*) results in doubled insets. Pick one approach — CSS is recommended for Blazor.

5. Missing viewport-fit=cover in Blazor. Without this meta tag, CSS env(safe-area-inset-*) values are always zero on iOS.

6. Assuming .NET 9 behavior on Android. After upgrading to .NET 10, Android ContentPage defaults to None (was effectively Container). Add SafeAreaEdges="Container" to restore the previous behavior.

7. Using legacy ios:Page.UseSafeArea in new code. The old API is iOS-only and obsolete. Always use SafeAreaEdges for cross-platform safe area management.

Checklist

• Android upgrade: SafeAreaEdges="Container" added if content goes under status bar
• Edge-to-edge: None set on both page and layout
• ScrollView keyboard avoidance uses wrapper Grid, not ScrollView's own SafeAreaEdges
• Blazor Hybrid: using either XAML or CSS safe areas, not both
• viewport-fit=cover in Blazor's index.html <meta viewport> tag
• Legacy UseSafeArea / IgnoreSafeArea migrated to SafeAreaEdges
