Avalonia App Development

Overview

Avalonia app entry: Program.cs builds and runs an AppBuilder. App.axaml + App.axaml.cs is the root. Platform lifetime determines how the app runs (Desktop vs Single-view for mobile/WASM).

Program.cs

using Avalonia;
// using ReactiveUI.Avalonia;  // (12.0+) ReactiveUI.Avalonia package — only if using ReactiveUI
// using Avalonia.ReactiveUI;  // (11.x) Avalonia.ReactiveUI package, last release 11.3.x

class Program
{
    [STAThread]
    public static void Main(string[] args) => BuildAvaloniaApp()
        .StartWithClassicDesktopLifetime(args);
