I am working in VS 2017, and I create a new console app in .Net Core 2.1. I use the nuget package manager to add PeterKottas.DotNetCore.WindowsService to my dependencies. Then I paste your example into Program.cs:

using System;
using System.Runtime;

using PeterKottas.DotNetCore.WindowsService;
using PeterKottas.DotNetCore.WindowsService.Interfaces;

namespace KottasTest
{
class Program
{
static void Main(string[] args)
{
ServiceRunner.Run(config =>
{
var name = config.GetDefaultName();
config.Service(serviceConfig =>
{
serviceConfig.ServiceFactory((extraArguments, x) =>
{
return new ExampleService();
});
serviceConfig.OnStart((service, extraArguments) =>
{
Console.WriteLine("Service {0} started", name);
service.Start();
});

                serviceConfig.OnStop(service =>
                {
                    Console.WriteLine("Service {0} stopped", name);
                    service.Stop();
                });

                serviceConfig.OnInstall(service =>
                {
                    Console.WriteLine("Service {0} installed", name);
                });

                serviceConfig.OnUnInstall(service =>
                {
                    Console.WriteLine("Service {0} uninstalled", name);
                });

                serviceConfig.OnPause(service =>
                {
                    Console.WriteLine("Service {0} paused", name);
                });

                serviceConfig.OnContinue(service =>
                {
                    Console.WriteLine("Service {0} continued", name);
                });

                serviceConfig.OnShutdown(service =>
                {
                    Console.WriteLine("Service {0} shutdown", name);
                });

                serviceConfig.OnError(e =>
                {
                    Console.WriteLine("Service {0} errored with exception : {1}", name, e.Message);
                });
            });
        });
    }
}

public class ExampleService : IMicroService
{
    public void Start()
    {
        Console.WriteLine("I started");
    }

    public void Stop()
    {
        Console.WriteLine("I stopped");
    }
}

}

This runs as a console application, but when I attempt to install using the console (running as admin), it fails as shown below:

If I add an app.config file such as below, to try to do a binding redirect, the result is still an error.

”

to try a binding redirect to the version of System.Runtime that I see in my nuget packages folder (under my profile), which is 4.3.0.0, it fails as shown below:

Because the sample app is so simple, I am not sure what can be going on here. This seems very weird.

Thanks for any help you can offer.

P.S. I do not know why my description got formatted so oddly. Also I put in the xml of the app.config file but that seems to have disappeared from the description (maybe it doesn't like xml?).

For the record I will try pasting that in again;

Did not know that "close and comment" meant "close the whole issue." Sorry.

Here is the whole solution.

From Readme:
20. "Install the service using powershell: dotnet.exe $serviceDllPath action:install"
You can also try dotnet run action:install from project folder
