MVC 6 Hosted on IIS HTTP Error 500.19

Question

Am getting HTTP Error 500.19 when accessing MVC 6 app in IIS on Windows 10.

In IIS I have set the App pool to 'No Managed Code'

The app is hosted in the root of a new Web Site.

I published the app using Visual Studio 2015 with the following settings.

Configuration : Debug Target DNX Version: dnx-clr-win-x64.1.0.0-rc1-update1

The web.config is the boilerplate provided by Visual Studio

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="httpPlatformHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified"/>
    </handlers>
    <httpPlatform processPath="%DNX_PATH%" arguments="%DNX_ARGS%" stdoutLogEnabled="false" startupTimeLimit="3600"/>
  </system.webServer>
</configuration>

Any ideas what is going wrong?

Thanks

Mike

Windows Event Tracing. Start->Run->eventvwr and check Application logs. — Pankaj Kapare, Feb 11 '16 at 23:42
Thanks, thought that was what you meant not heard it referred to as ETW before. — Mike U, Feb 11 '16 at 23:44
500.19 error is due to invalid configuration (usually due to incorrect/unrecognised elements in web.config). Try adding app.UseDeveloperExceptionPage() in startup configuration if you haven't already added. That may give some clues. — Pankaj Kapare, Feb 11 '16 at 23:59

For RC2 and above, HttpPlatformHandler has been replaced by ASP.NET Core Module

Install the new module from here.

The announcement can be found here.

is that download x64? – pedrommuller Jul 29 '16 at 02:55
AFAIK it should work on both x64 and x86. I am currently using it on various x64 machines. – vefve Aug 02 '16 at 08:02

I followed the steps here https://docs.asp.net/en/latest/publishing/iis.html I had exactly the same error on Windows Server 2012 IIS 8.5. Then I set up HttpPlatform handler. And it worked. Thanks – oneNiceFriend May 17 '16 at 11:34
FYI I installed httpplatformhandler but didn't work but after installing ASP.NET Core Module it started work. My application is Asp.net core – Shinya Koizumi Jan 22 '17 at 19:01

You have to install the "Hosting Bundle Installer". Without this, IIS doesn't understand routing and cannot host your application.

Go to microsoft site "https://www.microsoft.com/net/download/dotnet-core/runtime-2.1.0-rc1" and install "Hosting Bundle Installer":

Before installing this you have to install the right version of runtime: https://www.microsoft.com/net/download/dotnet-core/runtime-2.1.0-rc1 Than install the right version of "Hosting Bundle Installer".

"Hosting Bundle Installer" is: .NET Core Windows Server Hosting bundle installs the .NET Core Runtime, .NET Core Library, and the ASP.NET Core Module. The module creates a reverse proxy between IIS and the Kestrel server on Windows platforms.
