Do.net Core 3.1 HTTP 错误 500.19 - 内部服务器错误

Question

I was trying to create a simple (default) Web API using do.net core 3.1 in Visual Studio 2019 using "ASP.NET Core Web Application".

Once I created the (default) application and I was able to run it on IIS Express by pressing F5 in Visual Studio.

Then I want to publish so I went to windows features and turned on IIS then configured it by installing "WebPlatformInstaller_x64_en-US.msi" and "do.net-hosting-3.1.2-win.exe" (for dot.net core).

Then I ran the following in command prompt:

net stop was /y
net start w3svc

I did the publish using "Default Web Site/Test" configuration pointing to host: http://localhost and Self Contain Package with DotNet Core 3.1.

Also created a Application pool with "No Managed Code"

When I went to http://localhost/Test I got the following error message:

Here is my Web.Config :

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
  <handlers>
    <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
  </handlers>
  <aspNetCore processPath="dotnet" arguments=".\TestApp.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>
<!--ProjectGuid: 63addee1-2c1f-4679-94f4-df9dc952d8f9-->

I'm not sure if this is relevant information, when I did Pass-through Authentication test in IIS I'm getting the following:

I tried so many different ways of publishing and they all at the end getting the above error message. How can we resolve this?

Answer 1

1. ensure corresponding Application Pool configured with No Managed Code
2. ensure you've installed .NET Core Hosting Bundle

Answer 2

IMO, I will say you take a look through this walkthrough:

https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-3.1

Try check if Windows Process Activation Service (WAS) is activated on your system (server).

Turn stdoutLogEnabled="true" to get more detailed error from the app in a log file. Or turn on Developer Error Page in your Startup.cs class.

Answer 3

At My case, I attach .NET Core 3.1 apps on IIS win server 2019

I have installed .net core 3.1 runtime, and Hosting bundle, but something goes wrong

when I check at local compter I am missing:

Microsoft.WindowsDesktop.App 3.1.23 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

After I install .net Core Desktop Runtime the error gone.

Maybe the runtime need another installer..

Answer 4

It turned out to be our server was not allowed to have IIS turned on. It was configured as a data server . I had to get special permission to run IIS, then everything seems to work fine.
