WinFormsXaml

Familiar WinForms API

Use Form, Label, TextBox, Button, and other native control names in XML, then work with their normal WinForms types in C#.

Clean code-behind

Keep each embedded XML interface beside a C# class with stable reactive bindings, simple snapshot fields, events, functions, and precise reload scopes.

Live shared presets

Switch themes, density, language, dimensions, text, and typed CLR values across one form or the complete application.

Fully styleable tabs

Own every TabView header and content color, border, padding, and spacing while preserving inherited LTR and RTL behavior.

Reusable components

Register typed C# controls or embedded XML fragments with bindable properties and use them as elements throughout the application.

Fast repeated data

Start with a simple ItemsControl and get keyed updates and progressive rendering. Opt into a bounded virtual viewport only for measured large-list workloads.

Responsive flex layout

Build rows and columns with alignment, wrapping, gaps, and weighted growth while keeping ordinary WinForms controls.

A normal WinForms form, written in XML

<Form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      </ItemsControl.ItemTemplate>
