C# asp.net核心HTTP错误503。服务不可用

事件查看器显示以下错误

“工作进程未能预加载.Net运行时版本，无托管代码。”

“工作进程未能正确初始化，因此无法启动。数据是错误。”

我可以从命令行运行dotnet website.dll并在web浏览器中查看它，但由于某些原因，IIS不运行asp.net核心网站

我已经从这里安装了windows托管dotnet core以及sdk

我已将.net clr版本设置为无托管代码

我将身份更改为管理员，以消除潜在的权限问题

此外，我不得不将.csproj更改为以下内容，以避免asp.net核心版本之间的冲突

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework> <PublishWithAspNetCoreTargetManifest>false</PublishWithAspNetCoreTargetManifest>
  </PropertyGroup>

netcoreapp2.0错误

什么类型的机器？尝试添加

web.config

，是否有任何详细错误？windows server 2016，我添加了一个web.config，但它不生成任何日志，我相信，因为问题是如何让asp.net core主机工作，因为实际的asp.net core网页正在从命令行工作，所以问题在IIS和kestrel之间（我想）在我的例子中，它就像一个管理员同事停止应用程序池一样简单，而该应用程序池正是该站点运行的基础！
