Console

Making a new console application is pretty easy. All you have to to is subclass Application and override the Main method. When you do this, make sure that you don't call base.Main! base.Main is what would otherwise create the OpenTK window!

using System;

namespace CollisionDetectionSelector.Samples {
    class ConsoleSample : Application {
        public override void Main(string[] args) {
            Console.WriteLine("Testing, testing");
            Console.WriteLine("No window should pop up");
            Console.WriteLine("Press any key to quit");
            Console.ReadKey();
        }
    }
}
