Question

发布ASP.Net Core项目失败，出现下一个错误：

"DestinationFiles" refers to 1 item(s), and "SourceFiles" refers to 2 item(s).
They must have the same number of items.

当我尝试将ASP.Net Core网站发布到Azure时出现错误。它在本地构建和运行良好。输出打印出来：

        Task Parameter:

Microsoft.NET.Publish.targets文件（相关部分，我相信）看起来像这样：

  </Target>

          OverwriteReadOnlyFiles="$(OverwriteReadOnlyFiles)"
          Retries="$(CopyRetryCount)"
          RetryDelayMilliseconds="$(CopyRetryDelayMilliseconds)"

          UseSymboliclinksIfPossible="$(CreateSymbolicLinksForPublishFilesIfPossible)">

      <Output TaskParameter="DestinationFiles" ItemName="FileWrites"/>

    </Copy>

  </Target>

我根据另一篇帖子更改了DestinationFiles="@(_ResolvedFileToPublishPreserveNewest -> '$(PublishDir)%(RelativePath)')"，但我仍然遇到同样的失败，而且我对此没有足够的了解，发现任何明显错误，有人能提供一些见解吗？如果这受到其他帖子中提到的没有解决方法的错误的影响，我可以尝试将该应用程序发布到可能更好的azure上吗？

ASP.Net核心项目的发布失败了＆＃34; DestinationFiles＆＃34;指的是1个项目，＆＃34; SourceFiles＆＃34;是指2项
