[Mono-dev] Using the System.Linq library

[Alejandro Serrano]

The C# compiler does not support extension methods yet. So you must call
the methods directly from the Queryable class, something like:

using System;
using System.Linq;
using System.Collections.Generic;

public class Bla {
	public static void Main() {
	 List<int> first  = new List<int>(new int[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 });
	 List<int> second = new List<int>(new int[] {             4, 5, 6,         10 });

	 IEnumerable<int> q = Queryable.Except(first, second); <== here it is
	 int x = Enumerable.Count<int>(first);

	 foreach (int num in q)
		  Console.WriteLine(num);
	}
}
