# Introduction > Copy-and-own .NET MAUI and Avalonia components with the ShellUI design system. Source: https://native.shellui.dev/docs/introduction ShellUI Native brings the [shadcn/ui](https://ui.shadcn.com) approach to native .NET apps. It's the sibling of [ShellUI](https://shellui.dev) for Blazor: the same design, the same theme tokens, as plain C# controls for **.NET MAUI** and **Avalonia**. There's no component package to depend on. The `shellui-native` CLI copies each component into your project as a C# file, with everything it needs, and from then on the code is yours to read and change. > **Release status** > > `ShellUI.Native.CLI` **0.2.0-beta.1** is on NuGet and installs every component for both .NET MAUI and Avalonia. It's still a prerelease, so APIs can change. Components added since that release are marked **Next release** on their pages. ## How it works - **Copy and own.** `shellui-native add dialog` writes `Dialog.cs`, its parts and the helpers they use into `Components/UI`. Change anything: the next `add` won't overwrite it unless you pass `--force`. - **One design on two platforms.** Components keep the same names, properties and variants on MAUI and Avalonia, so a screen reads the same on both. Where a platform does something differently, the component's page says so under **MAUI and Avalonia**. - **Theme tokens.** Every colour is a token (`Background`, `Primary`, `Border`, …) mirroring ShellUI's CSS variables. `ShellTheme` swaps the light and dark palettes at runtime, and you can override any token. See [Theming](https://native.shellui.dev/docs/theming.md). - **No native chrome.** Selects, pickers, sliders and overlays are drawn by the components, so they look the same on Windows, macOS, Linux, Android and iOS. - **Keyboard and focus.** A focus ring for keyboard users, Enter and Space on triggers, Escape to close the overlay on top, and focus kept inside open dialogs. ## About these docs Each component page has a live preview and the code for **MAUI** and **Avalonia**. The previews are rendered with ShellUI for Blazor, which shares the design, so they look like the native component without being it. Pick your platform with the **MAUI | Avalonia** switch on any page; every example on the site follows, and your choice is remembered. ## Next steps - [Installation](https://native.shellui.dev/docs/installation.md): Install the CLI and set up a MAUI or Avalonia project. - [Components](https://native.shellui.dev/docs/components.md): Browse all 81 components by category. - [Theming](https://native.shellui.dev/docs/theming.md): Tokens, light and dark mode, and custom colours. - [CLI](https://native.shellui.dev/docs/cli.md): Every command and option.
