Use the following code on both platforms:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace Server
    class Program
        static void Main(string[] args)
            HttpListener listener = new HttpListener();
            var context = listener.GetContext();
            StreamWriter writer = new StreamWriter(context.Response.OutputStream);
            catch (HttpListenerException)
                Console.WriteLine("Using .net");
            catch (IOException)
                Console.WriteLine("Using mono");

Now run it on Linux, open a browser and type "" and quickly hit "Stop". Same procedure on windows yields different exceptions.
It's not a huge thing, but it's annoying when the same code doesn't work on Linux.
