使用 /p:PublishSingleFile=true 标志发布时出错

Question

我正在尝试将我的程序压缩为单个可执行文件。我正在遵循此处指定的说明：https : //dotnetcoretutorials.com/2019/06/20/publishing-a-single-exe-file-in-net-core-3-0/

当我在没有 /p:PublishSingleFile=true 的情况下运行我的代码时，它可以工作但不会生成单个文件（如预期）。当我添加上述标志时，我得到以下信息：

C:\Program Files\dotnet\sdk\3.0.100-preview7-012821\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Publish.targets(801,5): error MSB4018: The "GenerateBundle" task failed unexpectedly. [C:\Users\igorc\Work\ZConsole\ZConsole\ZConsole.csproj]

我认为这是一个环境问题，所以我创建了一个“HelloWorld”控制台应用程序，并在那里运行相同的脚本，它工作并生成一个可执行文件。

所有项目都在.NETCORE3.0下编译。

这是我的 ZConsole.csproj 的样子：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <ApplicationIcon>logo.ico</ApplicationIcon>
    <StartupObject>ZConsole.ZConsole</StartupObject>

  </ItemGroup>

  <ItemGroup>
    <None Update="App.config">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>
  </ItemGroup>
</Project>

谢谢您的帮助！

为了调试这个问题，我发现取消选中“发布”选项中的单文件标志并检查输出目录中的库很有用。在我的具体情况下，我有两个引用多个相同 COM 互操作库（IWshRuntimeLibrary 等）的程序集。我最终以这样一种方式使用了引用库的嵌入互操作类型和复制本地标志，无论存在什么冲突，都不再存在了。
