Thank you very much CW2! Also, I have attached a simple class that defines the STM32F405RG pins.

using System;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;

namespace STM32F4
{
    public static class Pin
    {
        public static Cpu.Pin PA0 { get { return (Cpu.Pin)(0); } }
        public static Cpu.Pin PA1 { get { return (Cpu.Pin)(1); } }
        public static Cpu.Pin PA2 { get { return (Cpu.Pin)(2); } }
        public static Cpu.Pin PA3 { get { return (Cpu.Pin)(3); } }
        public static Cpu.Pin PA4 { get { return (Cpu.Pin)(4); } }
        public static Cpu.Pin PA5 { get { return (Cpu.Pin)(5); } }
        public static Cpu.Pin PA6 { get { return (Cpu.Pin)(6); } }
        public static Cpu.Pin PA7 { get { return (Cpu.Pin)(7); } }
        public static Cpu.Pin PA8 { get { return (Cpu.Pin)(8); } }
        public static Cpu.Pin PA9 { get { return (Cpu.Pin)(9); } }
        public static Cpu.Pin PA10 { get { return (Cpu.Pin)(10); } }
        public static Cpu.Pin PA11 { get { return (Cpu.Pin)(11); } }
        public static Cpu.Pin PA12 { get { return (Cpu.Pin)(12); } }
        public static Cpu.Pin PA13 { get { return (Cpu.Pin)(13); } }
        public static Cpu.Pin PA14 { get { return (Cpu.Pin)(14); } }
        public static Cpu.Pin PA15 { get { return (Cpu.Pin)(15); } }
        public static Cpu.Pin PB0 { get { return (Cpu.Pin)(16 + 0); } }

        public static Cpu.Pin PB2 { get { return (Cpu.Pin)(16 + 2); } }
        public static Cpu.Pin PB3 { get { return (Cpu.Pin)(16 + 3); } }
        public static Cpu.Pin PB4 { get { return (Cpu.Pin)(16 + 4); } }
        public static Cpu.Pin PB5 { get { return (Cpu.Pin)(16 + 5); } }

        public static Cpu.Pin PB9 { get { return (Cpu.Pin)(16 + 9); } }
        public static Cpu.Pin PB10 { get { return (Cpu.Pin)(16 + 10); } }
        public static Cpu.Pin PB11 { get { return (Cpu.Pin)(16 + 11); } }
        public static Cpu.Pin PB12 { get { return (Cpu.Pin)(16 + 12); } }
        public static Cpu.Pin PB13 { get { return (Cpu.Pin)(16 + 13); } }
        public static Cpu.Pin PB14 { get { return (Cpu.Pin)(16 + 14); } }
        public static Cpu.Pin PB15 { get { return (Cpu.Pin)(16 + 15); } }
        public static Cpu.Pin PC0 { get { return (Cpu.Pin)(32 + 0); } }
        public static Cpu.Pin PC1 { get { return (Cpu.Pin)(32 + 1); } }
        public static Cpu.Pin PC2 { get { return (Cpu.Pin)(32 + 2); } }
        public static Cpu.Pin PC3 { get { return (Cpu.Pin)(32 + 3); } }
        public static Cpu.Pin PC4 { get { return (Cpu.Pin)(32 + 4); } }
        public static Cpu.Pin PC5 { get { return (Cpu.Pin)(32 + 5); } }
        public static Cpu.Pin PC6 { get { return (Cpu.Pin)(32 + 6); } }
        public static Cpu.Pin PC7 { get { return (Cpu.Pin)(32 + 7); } }

        public static Cpu.Pin PD2 { get { return (Cpu.Pin)(48 + 2); } }
    }
}

Awesome, glad I could help! Also, please mark this topic as "answered" if you can.
