C#

First post, so please go easy on me.

class Program
{
    static void Main()
    {
        new System.Diagnostics.StackTrace().GetFrame(0).GetMethod().Invoke(null, null);
    }
}

class Program
{
    static void Main()
    {
        new System.Diagnostics.StackTrace().GetFrame(0).GetMethod().Invoke(null, null);
    }
}

This simply creates a stack trace, grabs the top frame (which will be our last call to Main()), gets the method, and invokes it.
