After a couple of frustrating days trying to get the SPI interface to work, I ran across a post by Brett Wilson about using the shield with an I2C interface.
In his post he plugged the shield into a proto-board. I wanted to keep it attached to my FezPanda (.NET Micro, Arduino clone).
The attached PDF details the hardware mods to use the shield with the I2C interface. I will post NETMF C# code soon.
