"The " TransformWebConfig " task failed unexpectedly" on dotnet publish

我在发布 ASP.NET Core 2.0 Web应用程序时遇到问题。

实际上，该项目是我正在构建的开源模板。您可以在以下位置查看： https://github.com/diegoortizmatajira/aspnetboilerplate_template

应用程序构建并运行良好，但是当我执行dotnet发布命令时，它会显示一个meesage：

"转换WebConfig"任务意外失败。

应用程序不需要 web.config 文件(在 IIS 中使用(，因为它应该在 linux docker 容器中运行。

执行结果显示如下：

我的开发设置是：

但是，在容器内发布时也会失败。

我遇到了同样的问题，我在下面的问题中使用了"Andy Raddatz"中的answared修复："TransformWebConfig"任务意外失败 - System.Exception： AspNetCoreModuleHostingModel 属性的可接受值为

只需将此代码添加到您的应用程序".csproj"中：

<PropertyGroup>
  <IsTransformWebConfigDisabled>true</IsTransformWebConfigDisabled>
</PropertyGroup>

这是一个

错误:(尝试更新您的视觉工作室。如果它不能解决您的问题。您可以在 Web 项目中编辑 .csproj 文件并删除此行：

<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>

什么是进程内托管模型？
