Deploying Seq on IIS

Question

I'm trying to Deploy Seq by Datalust on IIS and I'm getting this error message:

HTTP Error 500.30 - ANCM In-Process Start Failure

here is the error in windows event viewer

Failed to start application '/LM/W3SVC/2/ROOT', ErrorCode '0x8007023e'.

here is the web.config file:

<?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=".\Seq.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>

the official documents are only available for deployment on Azure using Docker image or self hosted Kestrel application. Is my approach possible?

Answer 1

Seq's Windows hosting infrastructure uses HTTP.sys and not the ASP.NET Core/IIS integration, so this is not possible as far as we know, today.

IIS can be used as a reverse proxy in front of Seq, however, which covers some of the scenarios in which you might want to do this.
