我正在尝试添加新的 WinUI 2.4 ProgressRing。它在 UWP 应用程序上完美运行，但在 WASM 中不显示。
我的 App.xaml 和 Mainpage.xaml 是：
应用程序.xaml：
<Application

<ResourceDictionary>

<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
</ResourceDictionary.MergedDictionaries>
<Color x:Key="SystemAccentColor">#FFCB2128</Color>
<Color x:Key="AcmGreen">#FFB8C282</Color>

<Color x:Key="AcmPurple">#FF71749E</Color>
<Thickness x:Key="PivotItemMargin">0</Thickness>
</ResourceDictionary>

</Application>
MainPage.xaml：

在 UWP 中完美运行：
这里没有任何 ProgressRing 可用，与 UWP 不同。
如Uno Platform 2.3 博客文章中所述，ProgressRing 在 WASM 上不可用，就像在 UWP 上一样。它应该是。
Nuget 包版本：
- Uno.UI.RemoteControl {2.4.0}
- Uno.Wasm.Bootstrap {1.2.0}
- Uno.Wasm.Bootstrap.DevServer {1.2.0}
- Microsoft.Extensions.Logging.Filter {1.1.2}
- Microsoft.Extensions.Logging.Con... {1.1.1}
- NETStandard.Library {2.0.3}
- Uno.UI {2.4.0}
- Microsoft.NETCore.UniversalWindo... {6.2.10}
- Microsoft.Extensions.Logging.Con... {1.1.1}
- Microsoft.Extensions.Logging.Filter {1.1.2}
- Microsoft.UI.Xaml {2.4.0}
- Uno.Core {2.0.0}
我怎样才能解决这个问题 ？谢谢。
