SettingsPropertyHelper class¶

Summary¶

Lightweight sync-readable wrapper around a settings SettingsStream. Exposes a latest-value Value accessor (so derived SettingsStorage classes can still publish plain-C# properties), an IObservable surface (so reactive consumers can subscribe), a Set method (for writes), INotifyPropertyChanged notifications (so WPF/MAUI data bindings to BoolTest.Value update automatically), and an implicit conversion to T (so comparisons and assignments read naturally without .Value).

Remarks¶

Deliberately simpler than ReactiveUI's ObservableAsPropertyHelper<T> — no scheduler plumbing, no thrown-exception observable, no deferred subscription mode. Settings properties are long-lived, low-frequency, and single-subject; the extra ceremony buys nothing here.

Typical derived usage:

public sealed class MySettings : SettingsBase
 {
 public MySettings() : base(nameof(MySettings))
 {
 Enabled = CreateProperty(true, nameof(Enabled));
 }
 
 public SettingsPropertyHelper<bool> Enabled { get; }
 }
 
 // Consumers
 bool enabled = settings.Enabled; // implicit conversion, sync
 var current = settings.Enabled.Value; // explicit sync read
 if (settings.Enabled) { ... } // condition, implicit
 settings.Enabled.Subscribe(v => Log(v)); // reactive
 await settings.Enabled.Set(false); // write + commit
