## CommunityToolkit.Mvvm Source Generators

Use partial properties (CommunityToolkit.Mvvm 8.4+). The legacy field form emits **MVVMTK0045** in WinRT/WinUI projects.

```csharp
public partial class SettingsViewModel : ObservableObject
{
[ObservableProperty] private string _userName = string.Empty;
[ObservableProperty] public partial string UserName { get; set; }
[RelayCommand] private async Task SaveAsync() => await _service.SaveAsync(UserName);
}
```
