Include Styles in application:

<Application...
    xmlns:semi="https://irihi.tech/semi"
    xmlns:u-semi="https://irihi.tech/ursa/themes/semi"
    ....>

    <Application.Styles>
        <semi:SemiTheme Locale="zh-CN" />
        <u-semi:SemiTheme Locale="zh-CN"/>
    </Application.Styles>

You can now use Ursa controls in your Avalonia Application.

<Window
    ...
    xmlns:u="https://irihi.tech/ursa"
    ...>
    <StackPanel Margin="20">
        <u:ButtonGroup Classes="Solid Warning">
            <Button Content="Hello" />
            <Button Content="World" />
        </u:ButtonGroup>

    x:TypeArguments="TViewModel"
    ...>
...
</u:ReactiveUrsaWindow>
