QUESTION: Could you explain the execution result of this code?

To write parallel code is not a trivial task. There are details to consider and rules to observe.

Could you say the execution result of the following code? Could you explain why?

using System.Threading.Tasks;
using static System.Console;
class Program
{
    static void Main()
    {
        for (var i = 0; i < 10; i++)
        {
            Task.Factory.StartNew(() => WriteLine(i));
        }

        ReadLine();
    }
}

Share your thoughts in the comments. I will explain what is going on in a future post.
