 ## Is Uno.UI's Performance on WebAssembly going to improve
 Yes! The current performance is bound the runtime interpreted mode of mono-wasm. The Mono is working on implementing **AOT** compilation, which will improve significantly the performance. See [Miguel de Icaza's status update](https://gitter.im/aspnet/Blazor?at=5b1ab670dd54362753f8a168) for more details.

 No, not at the moment. Our assumption for now is that the WebAssembly part of Uno.UI will be efficient for it to be a viable alternative, but if you find that native support still is a viable scenario, please open a GitHub issue.

 For live update on UWP you need to edit the xaml while the project is debugging, no need for save, it updates on every keystroke (more or less) you need to update to the latest UWP sdk in your project configuration, change target version to latest

 That's exactly right, see [this](https://github.com/nventive/Uno/blob/a69879a3154f61b2d493be433aa08bc3b8aa1b06/src/Uno.UI/UI/Xaml/Style/Generic/Generic.xaml#L2843) for the XAML-UWP button, and [this](https://github.com/nventive/Uno/blob/a69879a3154f61b2d493be433aa08bc3b8aa1b06/src/Uno.UI/UI/Xaml/Style/Generic/Generic.Native.xaml#L20) for the iOS native button When complete XAML is used for rendering, it's not so much a conversion but more of  a vector rendering. For instance, Uno.UI.iOS uses CGLayer for rendering content it's different because Uno.UI integrates within the layouting system of the platform, which allows for mixed rendering. Uno.UI supports webviews, whereas Flutter does not. Flutter also has to render everything, including what the platform provides by default, such as the Magnifier in the TextBox for accessibility (they is not yet supported either).
