Welcome to the community!
Is anything plugged into the shield when you plug the shield into your Netduino?
Do you know if the shield is 3.3V compatible? Many shields are designed to work with both 3.3V devices (like Netduino) but some only work with 5V devices.
I looked on a few websites, including the manufacturer's website, and didn't see any schematics; do you have a link we could take a look at?
I actually emailed Seeed Studio about it and got this back:
Electronic Brick Chassis v1.1 can pull 5v or 3.3v.
So it looks like it's not the voltage. I forgot to ask for a schematic. Silly me.

Hi greg, can you get a schematic for the board?
Netduino can supply both 5V and 3.3V -- but the big question is what are they feeding back and to where...
I emailed them back this morning asking for a schematic. They are based in China so we'll see when I get a reply. They were pretty quick on my first request.

Hi Guys, thanks for the coop!
This is as close as I could get to a schematic:
Page 4, Electronic Brick Chassis.
I believe I was using D8 and D9, with a momentary switch and an LED brick on each, respectively.
I'm sorry, I didn't do quite as thorough a debug job as I am capable of. My electronics skills are limited as of yet and the last thing I want to do is start my embedded micro journey by shorting my board.
Got the schematics from them. Attached.

I'm going to try again as soon as I get a chance. I was trying to get the brick led to turn on and off in response to brick switch's input. I modified the netduino onboard led+switch code using the proper input and output pins as a first attempt to step into using the "real" pins.
Seems to work fine. My only gripe about the brick is separating all the sensors - dremel with a cutoff wheel will take care of that though.
