How set Beyond Compare ignore summary comments .net

Question

I need that Beyond Compare 4 only compare code and not summary comments like

    /// <summary>
    /// Instancia estática del contenedor.
    /// </summary>
    public static ComponentContainer Instance
    {
        get { return ComponentContainer._instance; }
    }

    /// <summary>
    /// Inicializa la instancia estática del contenedor.
    /// </summary>
    public static void Initialize()
    {
        if (!IsInitialized)
            _instance = new ComponentContainer();
    }

And other code:

    /// <summary>
    /// Instancia estática del contenedor xx
    /// </summary>
    public static ComponentContainer Instance
    {
        get { return ComponentContainer._instance; }
    }

    /// <summary>
    /// Inicializa la instancia estática del contenedor.
    /// </summary>
    public static void Initialize()
    {
        if (!IsInitialized)
            _instance = new ComponentContainer();yyyy
    }

The idea is that only the Beyond Compare show diference in the line yyyy and not the line xx.
