How to create a web.config for a non ASP.net executable in IIS?

I need to host an API I wrote in Rust with IIS, I have never used IIS. Everyone else I have spoke to has been using .NET and found it to be pretty much just plug and play.

Any time I create a web.config file based on https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/web-config?view=aspnetcore-7.0 I get a 500.19 internal server error. If I do not create a web.config I presume it isn't even trying to do anything and I get 403.14 Forbidden.

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

The above was basically what I used that gave me the 500.19 error, and within IIS it complains that it cannot read the configuration file at all which is rather annoying considering I got this config off of microsoft's documentation.

Solution

HttpPlatformHandler was the answer, thank you Microsoft for making that so hard to find. You do not have to use reverse proxy, FastCGI, switch to .NET or anything like that.
