OWIN in ASP.NET Core? ASP.NET Core vs selfhost ASP.NET

Yes. In fact, all ASP.NET Core applications are self-hosted. Even in production, IIS/Nginx/Apache are a reverse proxy for the self-hosted application.

In a reasonably standard Program.cs class, you can see the self-hosting. The IISIntegration is optional - it's only necessary if you want to integrate with IIS.

public class Program
{
    public static void Main(string[] args)
    {
        var config = new ConfigurationBuilder()
            .AddCommandLine(args)
            .AddEnvironmentVariables(prefix: "ASPNETCORE_")
            .Build();

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

        host.Run();
    }
}

Middleware is quite similar between Katana and Core but you use HttpContext instead of IOwinContext.
Startup.cs is similar but there's much more DI support.
WebApi has been merged into MVC
DelegatingHandler is gone, use middleware instead.
HttpConfiguration has been split up into Routing and MvcOptions.
