FmgLib.MauiMarkup 10.1.2

FmgLib.MauiMarkup

FmgLib.MauiMarkup is a fluent C# markup library for .NET MAUI: build your entire UI in pure C# — no XAML. Every bindable property of every MAUI control gets a chainable extension method with the same name, and every event gets an On<EventName> method, with full IntelliSense, refactoring and compile-time safety.

public partial class MainPage : ContentPage, IFmgLibHotReload
{
    int count = 0;

    public MainPage() => this.InitializeHotReload();

    public void Build() =>
        this.Content(
            new VerticalStackLayout()
            .Spacing(25)
            .Padding(30)
            .Center()
            .Children(
                new Label()
                    .Text("Hello, World!")
                    .FontSize(32)
                    .CenterHorizontal(),

                new Button()
                    .Text("Click me")
                    .OnClicked(b => b.Text = $"Clicked {++count} times")
                    .CenterHorizontal()
            )
        );
}

Quick Start

New project (recommended):

dotnet new install FmgLib.MauiMarkup.Template
dotnet new fmglib-mauimarkup-app -o MyApp

Existing MAUI project:

dotnet add package FmgLib.MauiMarkup

No registration call needed. XAML and FmgLib pages coexist, so you can migrate incrementally.

Key Features

• Every control, every property, every event — fluent methods for the whole MAUI surface, always in sync with the referenced MAUI version.
• Third-party controls too — [MauiMarkup(typeof(...))] or <MauiMarkupSourceGenerator>true</MauiMarkupSourceGenerator> generates the same fluent API for Syncfusion, UraniumUI, SkiaSharp, ZXing, DevExpress, InputKit…
• Hot reload built in — implement IFmgLibHotReload, call InitializeHotReload(), and your Build() re-runs on every code edit (leak-free, crash-isolated, works with dotnet watch and IDE hot reload).
• First-class bindings — string paths or compiled Getter expressions, inline converters, multi-binding.
• Theming — OnLight/OnDark, OnPlatform, OnIdiom, DynamicResource on any property; strongly-typed Style<T> with triggers and visual states.
• Localization — JSON or RESX based, with instant runtime language switching.
