当我部署应用程序时，遇到了同样的问题。这是由于我的一些问题导致的 :)
我仔细阅读了这个页面：
ASP.NET Core: Publishing to IIS
首先，我没有安装
.NET Core Windows Server Hosting bundle的所有部分。最后，我进行了一个面向框架的部署而不是自包含的部署。我们有很多应用程序，并且不希望/需要它们各自拥有 .net core 的版本。在服务器上会有太多版本的 .net。
此外，请注意，如果您的管理员对服务器执行了任何更新/升级操作，则可能会破坏您的ASP.NET Core安装（请参见
ASP.NET Core: Publishing to IIS故障排除部分）。
然后，我不得不修复我的web.config……这是我正在使用的已发布的web.config：
我没有发布为*.exe，而是使用了*.dll（请注意我的arguments值）。另外，我的processPath设置为“dotnet”。
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath="dotnet" arguments=".\DT.Web.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false" />
</system.webServer>
</configuration>
此外，请确保您的 project.json 选项都与服务器环境兼容（参见
ASP.NET Core：发布到 IIS 故障排除部分）。
如果有帮助，这是我的 project.json 的副本：

<AspNetCoreModuleName>AspNetCoreModule</AspNetCoreModuleName>更改为AspNetCoreModuleV2，然后它将读取processPath="%LAUNCHER_PATH%"。 - Pierre
