## ๐ฆ Installation
Add to your `Cargo.toml`:
```toml
[dependencies]
winrt-xaml = "0.1.0"
```
## ๐ฏ 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(())
}
```

## โก Performance
WinRT-XAML provides **minimal FFI overhead** with zero-cost abstractions:
| 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
## ๐ง 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
```
