Question

我正在尝试将程序压缩为单个可执行文件。我正在按照此处指定的说明进行操作：https://dotnetcoretutorials.com/2019/06/20/publishing-a-single-exe-file-in-net-core-3-0/

当我在不使用/ p：PublishSingleFile = true的情况下运行代码时，它可以工作，但未生成单个文件（按预期）。当添加上述标志时，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，因此我创建了一个“ HelloWorld”控制台应用程序，并在其中运行了相同的脚本，它起作用并生成了一个可执行文件。

所有项目均在.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>
    <PackageRequireLicenseAcceptance>false</PackageRequireLicenseAcceptance>
    <GeneratePackageOnBuild>false</GeneratePackageOnBuild>
    <RuntimeIdentifier>win10-x64</RuntimeIdentifier>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <PublishTrimmed>true</PublishTrimmed>
  </PropertyGroup>

    <PackageReference Include="log4net-loggly" Version="9.0.0" />

    <PackageReference Include="Topshelf" Version="4.2.1" />
    <PackageReference Include="WebSocketSharp-NonPreRelease" Version="1.0.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\ZWaveDll\BasicApplication\BasicApplication_netcore.csproj" />
    <ProjectReference Include="..\ZWaveDll\Utils\Utils_netcore.csproj" />
    <ProjectReference Include="..\ZWaveDll\ZWaveXml\ZWaveXml_netcore.csproj" />
    <ProjectReference Include="..\ZWaveDll\ZWave\ZWave_netcore.csproj" />
  </ItemGroup>

  <ItemGroup>
    <Compile Update="AssemblyInfo.cs">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Compile>
  </ItemGroup>

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

感谢您的帮助！

Answer 1

为了调试此问题，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。在我的特定情况下，我有两个程序集引用了多个相同的COM互操作库（IWshRuntimeLibrary等）。我最终使用了所引用库的Embed Interop Types和Copy Local标志，使之不再存在任何冲突。

Answer 2

添加

<CopyLocalLockFileAssemblies>false</CopyLocalLockFileAssemblies>

.csproj解决了发布问题

参考 https://github.com/dotnet/runtime/issues/3735#issuecomment-666641134

禁用 NLog.config 的 CopyToOutputDirectory 后，发布到单个文件工作正常。

<None Include="NLog.config" />
      <!--<CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>-->

使用/ p：PublishSingleFile = true标志发布时出错
