the minimal request csproj properties for creating an unpackage desktop winui app

App1.csproj

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net9.0-windows10.0.26100.0</TargetFramework>
    <UseWinUI>true</UseWinUI>
    <Nullable>enable</Nullable>
    <ImplicitUsings>true</ImplicitUsings>
    <ApplicationManifest>app.manifest</ApplicationManifest>
  </PropertyGroup>
  
  <PropertyGroup>
    <EnableMsixTooling>true</EnableMsixTooling>
    <WindowsAppSDKSelfContained>true</WindowsAppSDKSelfContained>
    <Platforms Condition="'$(WindowsAppSDKSelfContained)' == 'true'">x64;ARM64</Platforms>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Windows.SDK.BuildTools" Version="10.0.26100.1742" />
    <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.6.250205002" />
    <PackageReference Condition="'$(PublishAot)' == 'true'" Include="Microsoft.Web.WebView2" Version="1.0.3065.39" />
  </ItemGroup>
</Project>

1. 引用新版本的 WebView2 是为了避免 AOT 编译时发出的警告
2. EnableMsixTooling 是为了启用 dotnet cli
3. WindowsAppSDKSelfContained 设置为 false 会导致框架初始化设置同步上下文时 COMException: 没有注册类 0x80040154
4. Platforms 是为了避免因 WindowsAppSDKSelfContained 引起的 VS 找不到架构的错误警告

要使用 dotnet cli build 需要指定架构如 -r win-x64

没有 launchSetting.json 的前提下 好像就需要 <WindowsPackageType>None</WindowsPackageType> 这个
