Deploying a ASP.Net Core web application via IIS

I am having trouble deploying a ASP.Net Core 2.0 web application via IIS. My application builds and runs through VS but I cannot get the IIS instance to work.

I get the following error message:

HTTP Error 502.5 - Process Failure 

Common causes of this issue: 

- The application process failed to start 
- The application process started but then stopped 
- The application process started but failed to listen on the configured port 

None of the troubleshooting steps have worked. I do not think the problem is with the application itself as when I run the following through command line:

"C:\Program Files\dotnet\dotnet.exe" C:\inetpub\wwwroot\MyApp\MyApp.dll

The application runs and I can view it at http://localhost:5000/

I have been through all the steps at https://learn.microsoft.com/en-gb/aspnet/core/host-and-deploy/iis/index?tabs=aspnetcore1x#common-errors and still have not made any progress.

This is what my WebHostBuilder method looks like:

var host = new WebHostBuilder()
              .UseKestrel()
              .UseContentRoot(Directory.GetCurrentDirectory())
              .UseIISIntegration()
              .UseStartup<Startup>()
              .UseApplicationInsights()
              .Build();
host.Run();

and I use the following settings in my Startup.cs:

services.Configure<IISOptions>(options =>
{
    options.AutomaticAuthentication = true;
});
