Kestrel configuration to use a specific port + url

I am using Asp.Net core 2.0.2 on Win 7 with VS2017 (15.3.5).

My current Kestrel configuration looks like this:

return WebHost.CreateDefaultBuilder(args)
    .UseStartup<Startup>()
    .ConfigureAppConfiguration((hostContext, config) =>
    {
        var envName = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");

        config.Sources.Clear();
        config.AddJsonFile("appsettings.json", optional : false);
        config.AddJsonFile($"appsettings.{envName}.json", optional : false);
        config.AddEnvironmentVariables();
    })
    .UseKestrel(options =>
    {
        options.Listen(IPAddress.Loopback, 5859);
    })
    .UseContentRoot(pathToContentRoot)
    .Build();

This obviously listens on http://localhost:5859. I want to configure Kestrel so that it ONLY listens on a custom URL such as http://localhost:5859/MyNewApp. How do I do that?

(With Core 1.0, I had used UseUrls("http://localhost:5859/MyNewApp") which partially did the job. It would listen on http://localhost:5859 as well as http://localhost:5859/MyNewApp. Doing the same in Core 2.0.2 results in an exception:

System.InvalidOperationException: A path base can only be configured using IApplicationBuilder.UsePathBase())

With 2.0 you need to leverage UsePathBase as UseUrls was removed from Kestrel. You'll want to do this in your Configure method at startup:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UsePathBase("/MyNewApp"); 
}
