Dotnet Core 3.1 HTTP Error 500.19 - Internal Server Error

Question

I was trying to create a simple (default) Web API using dotnet 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 "dotnet-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?

Have you installed the ASP.NET Core Hosting Bundle, and restarted the W3SVC service to refresh the PATH variable? — ColinM, Mar 23 '20 at 16:58
I have installed the latest and did the following by running CMD under admin mode: net stop was /y then net start w3svc — Ranch Camal, Mar 23 '20 at 21:17
Run some basic diagnostics, https://docs.jexusmanager.com/tutorials/ancm-diagnostics.html — Lex Li, Mar 23 '20 at 22:46
JexusManager is throwing the exact same issue when I try to open the web.config with it. — Ranch Camal, Mar 24 '20 at 04:19
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. — Ranch Camal, Jun 25 '20 at 21:50

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

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

https://learn.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.

I did turn it on but then I realized my error is saying that it's having issues with Web.config. So not sure if it can even read the stdoutLogEnabled="true" configuration. – Ranch Camal Mar 24 '20 at 04:10
Oops, U can try this as a follow up, I know its 2.** solution but it should work for this situation too I guess. https://bytutorial.com/blogs/asp-net-core/http-error-50019---internal-server-error-when-publishing-aspnet-core-web-api-to-iis-server https://stackoverflow.com/questions/40805402/http-error-500-19-when-publish-net-core-project-into-iis – Ismail Umar Mar 24 '20 at 07:55

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..
