ASP.Net Core 项目发布失败，“DestinationFiles”引用 1 个项目，“SourceFiles”引用 2 个项目

Question

ASP.Net Core 项目的发布失败并出现以下错误：

"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。它在本地构建并运行良好。输出打印如下：

Task "Copy"
        Task Parameter:

Microsoft.NET.Publish.targets 文件（我相信相关部分）如下所示：

我已经根据这里的另一篇文章进行了更改，DestinationFiles="@(_ResolvedFileToPublishPreserveNewest -> '$(PublishDir)%(RelativePath)')"但我仍然遇到同样的失败，而且我对此了解不够，无法发现任何明显的错误，任何人都可以提供一些见解吗？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，我可以尝试哪些替代方法将应用程序发布到 azure，可能效果更好？
