Server has to know where your startup class is

One option is like Rob wrotes:

[assembly: OwinStartup(typeof(MyStartupClass))]

But there are other possibilies up to your requiremens. From Microsoft Docs (docs.microsoft.com/en-us/aspnet/core/fundamentals/startup):

Alternatively, you can define a fixed Startup class that will be used regardless of the environment by calling UseStartup. This is the recommended approach.

Example:

public class Program
    {
        public static void Main(string[] args)
        {     
          BuildWebHost(args).Run();   
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup()
                .Build();
    }
