## What it does

This skill teaches the assistant how to use the cross-platform safe area API introduced in .NET 10. It focuses on the `SafeAreaEdges` struct and `SafeAreaRegions` flags enum (`None`, `SoftInput`, `Container`, `All`), which replace legacy iOS-only `UseSafeArea` and layout-level `IgnoreSafeArea` properties.

Upgrading to .NET 10 breaks previous Android layout assumptions: `ContentPage` now defaults to `None` across platforms, rendering views directly under the status bar. The skill provides XAML Thickness-style syntax examples to configure uniform or per-edge insets, handle immersive media views, and avoid soft input keyboard overlap.

The new APIs require target framework `net10.0-*` or later. If your project targets .NET 9 or earlier, these types do not exist, and the skill falls back to legacy platform properties. Windows does not use system bar insets.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-safe-area -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/maui-safe-area/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/maui-safe-area/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-safe-area -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/maui-safe-area/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-safe-area -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/maui-safe-area/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dotnet/skills maui-safe-area
```

2. **Manually: put the files in place**
- File: `.github/skills/maui-safe-area/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-safe-area -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dotnet/skills --path plugins/dotnet-maui/skills/maui-safe-area
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/maui-safe-area/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-safe-area -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dotnet/skills/tree/HEAD/plugins/dotnet-maui/skills/maui-safe-area/SKILL.md

## When to use it
- prevent UI content from sliding under the status bar, notch, or Dynamic Island
- configure edge-to-edge screens for media players and maps
- adjust layouts automatically when the on-screen keyboard opens
- migrate code from deprecated UseSafeArea and IgnoreSafeArea properties

## Example prompts
- Configure SafeAreaEdges for a chat screen so the entry box stays above the keyboard
- Why is my Android ContentPage overlapping the status bar after updating to .NET 10?
- Show how to set up an edge-to-edge header with safe body content in .NET 10 XAML

# 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

```csharp
[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
````
