为什么我的 Package.appxmanifest 扩展给我验证错误 C00CE014？

Question

在新的 Visual Studio 2019 解决方案中，我创建了一个 .Net Core 控制台项目和一个 UWP 项目，我正在使用 Windows 应用程序打包项目对其进行打包。在这个阶段，我能够毫无问题地编译和运行所有这些项目。

我的下一个任务是将控制台应用程序的编译输出作为 windows.fullTrustProcess 添加到打包项目的 Package.appxmanifest 中：

<?xml version="1.0" encoding="utf-8"?>

  </Applications>

  <Capabilities>
    <Capability Name="internetClient" />
    <rescap:Capability Name="runFullTrust" />
    <rescap:Capability Name="allowElevation" />
  </Capabilities>

  <Extensions>
    <uap3:Extension Category="windows.fullTrustProcess" Executable="MyConsoleApp.exe"/>
  </Extensions>

</Package>

当我尝试构建打包项目时 我收到以下构建错误：

Error APPX0501: Validation error. error C00CE014: App manifest validation error: The app manifest must be valid as per schema: Line 40, Column 6, Reason: Element '{http://schemas.microsoft.com/appx/manifest/uap/windows10/3}Extension' is unexpected according to content model of parent element '{http://schemas.microsoft.com/appx/manifest/foundation/windows10}Extensions'. Expecting: {http://schemas.microsoft.com/appx/manifest/foundation/windows10}Extension, {http://schemas.microsoft.com/appx/manifest/foundation/windows10}ExtensionChoice.

我尝试了 Extension、uap:Extension、desktop:Extension 的不同组合，它们都给我类似的错误。我相信从根本上说我对 appxmanifest 命名空间的了解还不足以诊断问题。

如何正确声明我的 fullTrustProcess 扩展？

Answer 1

请将 Extensions 放在 Application 块内。

喜欢以下内容：

<Applications>
<Application Id="App" Executable="$targetnametoken$.exe" EntryPoint="$targetentrypoint$">
  <uap:VisualElements ....../>
  </uap:VisualElements>
  <Extensions>
    <desktop:Extension Category="windows.fullTrustProcess" Executable="FullTrust\FullTrust.exe" />
  </Extensions>
</Application>
