我有一个ASP.NET核心应用程序，在IIS Express中运行良好.同样，如果我通过dotnet run从命令行启动应用程序，一切都会顺利进行:

C:\Code\Sandbox\IisTestApp\IisTestApp>dotnet run
Using launch settings from C:\Code\Sandbox\IisTestApp\IisTestApp\Properties\launchSettings.json...
Hosting environment: Production
Content root path: C:\Code\Sandbox\IisTestApp\IisTestApp
Now listening on: http://localhost:5000
Now listening on: https://localhost:5001
Application started. Press Ctrl+C to shut down.

如果try 以本地IIS为目标，则会出现以下错误:

无法启动进程C:\Program Files\dotnet\dotnet.exe.web服务器请求失败，状态代码为500，内部服务器错误.完整响应已写入C:\Users{my user name}\AppData\Local\Temp\HttpFailure_08-05-50.html.

HTML文件包含以下信息:

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.个

Note: in case it's not obvious from that message, this is a minimal repro of my problem, not the actual app

我在网上看到的大多数错误代码都是0x8007000d，这表明我没有正确的答案.NET核心Windows服务器托管组件(AspNetCoreModule)，但我肯定已经安装了:

个

我还可以在IIS的主"模块"页面中看到它，并验证它指向的文件是否确实存在:

奇怪的是，如果我try 转到此特定站点的模块页面，得到的错误信息与该网页相同:

执行此操作时出错.

详细信息:

文件名:\？\C:\Code\Sandbox\IisTestApp\IisTestApp\web.配置

此托管模块版本(2.1.8)通常与我安装的内容相匹配:

C:\Users\{my user name}>dotnet --list-sdks
2.1.202 [C:\Program Files\dotnet\sdk]
2.1.504 [C:\Program Files\dotnet\sdk]

C:\Users\{my user name}>dotnet --list-runtimes
Microsoft.AspNetCore.All 2.1.4 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.8 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.4 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.1.8 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.0.9 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.8 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

我的测试应用的目标是:

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.1.2" PrivateAssets="All" />
  </ItemGroup>

</Project>

尽管如此，我认为问题确实与IIS和托管组件有关！这里是(默认的)网站.使用项目模板生成的配置:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="bin\IISSupport\VSIISExeLauncher.exe" arguments="-argFile IISExeLauncherArgs.txt" stdoutLogEnabled="false">
        <environmentVariables />
      </aspNetCore>
    </system.webServer>
  </location>
</configuration>

Note: I still get the same error message if I hardcode the full path in the processPath, or use 100 relative pathing

如果删除<aspNetCore> node ，则会出现另一个错误:

HTTP Error 502.3 - Bad Gateway

There was a connection error while trying to route the request.

Detailed Error Information:个

Module AspNetCoreModule
Notification ExecuteRequestHandler
Handler aspNetCore
Error Code 0x80070490
Requested URL http://localhost:80/IisTestApp
Physical Path C:\Code\Sandbox\IisTestApp\IisTestApp
Logon Method Anonymous
Logon User Anonymous

重点是AspNetCoreModule这次抛出了错误，所以它is正在加载并运行一些代码.

发布到单独的文件夹并在IIS中手动设置站点(而不是依赖于默认的Visual Studio行为，即创建指向"bin"文件夹的IIS网站)会导致相同的错误消息，尽管我在生成的web.config文件中得到的 node 略有不同:

<aspNetCore processPath="dotnet" arguments=".\IisTestApp.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout">
  <environmentVariables />
</aspNetCore>

What is causing IIS to fail to run this application?

我试过重新安装.NET核心(SDK、运行时和托管组件)，但它没有帮助.

我还注意到，有几篇帖子提到，为IIS安装URL重写模块可以纠正这个错误(尤其是:HTTP Error 500.19 - IIS 7.5 Error 0x8007000d).我的网络.config没有提到那个模块，但我试着安装它，以防AspNetCoreModule在幕后使用它.这对我的处境没有帮助.
