            This rule warns the developer if any virtual methods are called in the constructor
            of a non-sealed type. The problem is that if a derived class overrides the method
            then that method will be called before the derived constructor has had a chance
            to run. This makes the code quite fragile.
            </summary><remarks>This rule is available since Gendarme 2.0</remarks><example>
            Bad example:
            <code>
            class A {
            	public A ()
            	{
            		this.DoSomething ();
            	}

            	{
            	}
            }
            class B : A {
            	private int x;
            	public B ()
            	{
            		x = 10;
            	}
            	protected override void DoSomething ()
            	{
            		Console.WriteLine (x);
            	}
            }
            B b = new B (); // outputs 0 because B's constructor hasn't been called yet
            </code></example><example>
            Good example:
            <code>
            class A {
            	public void Run ()
            	{

            }
            class B : A {
            	private int x;
