如果我直接在Visual Studio中启动我的UWP应用程序（WLAN连接器），它工作正常。但是，如果我尝试在WPF程序中启动它，它将以正确的大小打开UWP窗口，但它只显示标准的splashscreen，它不会启动程序？我不知道怎么了？
安装Nuget PCage：NUGET Microsoft.Toolkit.Wpf.UI.XamlHost NUGET Microsoft.Windows.SDK.Contracts .NET 4.8
希望有人比我更有UWP的经验。谢啦，谢啦
下面你会发现洞项目，WPF启动程序和UWP应用程序，将无法从WPF应用程序正确启动，也许有人可以帮助我：

您可以使用Protocol在WPF中启动UWP。
1.在UWP项目的文件Package.appxmanifest中定义协议名称。

  1. <Extensions>
  2.   <uap:Extension Category="windows.protocol">
  3.      <uap:Protocol Name="uwptestapp">
  4.          <uap:DisplayName>UWP-Test-app</uap:DisplayName>
  5.      </uap:Protocol>
  6.   </uap:Extension>
  7. </Extensions>

字符串
1.覆盖App.xaml.cs中的Application.OnActivated。

  1. protected override void OnActivated(IActivatedEventArgs args)
  2. {
  3.     Frame rootFrame = Window.Current.Content as Frame;
  4.     if (rootFrame == null)
  5.     {
  6.         rootFrame = new Frame();
  7.         Window.Current.Content = rootFrame;
  8.     }
  10.     rootFrame.Navigate(typeof(MainPage));
  11.     Window.Current.Activate();
  12. }

1.使用LaunchUriAsync和协议名称在WPF中启动UWP。

  1. using Windows.System;
  3. private async void Button_Click(object sender, RoutedEventArgs e)
  4. {
  5.     var res=await Launcher.LaunchUriAsync(new Uri("uwptestapp:"));
  6. }

注意：要在桌面应用中调用Windows运行时API，您需要修改目标Framework。
右键单击您的WPF项目->选择Unload Project->修改TargetFramework。

  1. <Project Sdk="Microsoft.NET.Sdk">
  3.   <PropertyGroup>
  4.     <OutputType>WinExe</OutputType>
  5.     <TargetFramework>net6.0-windows10.0.22621.0</TargetFramework>
  6.     <Nullable>enable</Nullable>
  7.     <UseWPF>true</UseWPF>
  8.     <SupportedOSPlatformVersion>10.0.22621.0</SupportedOSPlatformVersion>
  9.   </PropertyGroup>
  11. </Project>
