## ๐Ÿ“ฆ Installation

Add to your `Cargo.toml`:

```toml
[dependencies]
winrt-xaml = "0.1.0"
```

## ๐ŸŽฏ Quick Start

### Try the Examples
```powershell
# Scrollable list with 30 items
cargo run --example scrollable_list

# Functional calculator
cargo run --example winrt_calculator_functional

# Chat interface
cargo run --example chat_interface

# Interactive counter
cargo run --example counter
```

### Create Your First App
```rust
use winrt_xaml::error::Result;
use winrt_xaml::xaml_native::*;
use windows::Win32::System::Com::{CoInitializeEx, COINIT_APARTMENTTHREADED};

fn main() -> Result<()> {
    // Initialize COM for WinRT
    unsafe {
        CoInitializeEx(None, COINIT_APARTMENTTHREADED).ok()?;
    }

    // Initialize XAML
    let _xaml_manager = XamlManager::new()?;

    // Create host window
    let hwnd = create_host_window("My App", 600, 400)?;

    // Create XAML source and attach
    let mut xaml_source = XamlSource::new()?;
    let island_hwnd = xaml_source.attach_to_window(hwnd)?;

    // Create UI
    let panel = XamlStackPanel::new()?;
    panel.set_vertical(true)?;
    panel.set_spacing(20.0)?;
    panel.set_background(0xFF1A1A1A)?; // Dark theme
    panel.set_padding(30.0, 30.0, 30.0, 30.0)?;

    let button = XamlButton::new()?;
    button.set_content("Click Me!")?;
    button.set_size(150.0, 50.0)?;
    button.set_background(0xFF0078D4)?; // Microsoft blue
    button.on_click(|| println!("Button clicked!"))?;

    panel.add_child(&button.as_uielement())?;
    xaml_source.set_content_element(&panel.as_uielement())?;

    // Show and run
    unsafe {
        ShowWindow(island_hwnd, SW_SHOW);
        ShowWindow(hwnd, SW_SHOW);
    }

    // Message loop...
    Ok(())
}
```

## โšก Performance

WinRT-XAML provides **minimal FFI overhead** with zero-cost abstractions:

| Operation | Performance | Notes |
|-----------|-------------|-------|
| FFI Function Call | ~5-10ns | Negligible overhead |
| String Conversion | ~100ns | UTF-8 to UTF-16 |
| Object Creation | ~1-5ฮผs | COM allocation |
| Event Dispatch | ~50-100ns | Callback invocation |

**Key Performance Features:**
- Zero-cost abstractions over WinRT
- RAII-based memory management (no GC)
- Direct C++/WinRT integration
- Incremental compilation support

## ๐Ÿ”ง Development

### Prerequisites

- **Rust** 1.70 or later
- **Windows** 10/11 (Version 10.0.19041.0+)
- **CMake** 3.15 or later
- **Visual Studio Build Tools** 2019 or later with "Desktop development with C++"
- **Windows SDK** 10.0.19041.0 or later

### Building

**Complete Build Process** (first time):

```powershell
# 1. Build C++ helper DLL
cd xaml_islands_helper
mkdir build
cd build
cmake ..
cmake --build . --config Debug
cd ../..

# 2. Build Rust library and examples
cargo build --all-targets

# 3. Run an example
cargo run --example scrollable_list
```

**Incremental Builds** (after initial setup):

```powershell
# Just rebuild Rust (C++ DLL already built)
cargo build --all-targets

# Rebuild specific example
cargo build --example chat_interface
```

**See [BUILD_SYSTEM.md](BUILD_SYSTEM.md) for comprehensive build documentation.**

### Testing

```powershell
# Run tests (when implemented)
cargo test --lib

# Test by running examples
cargo run --example scrollable_list
```
