First you'd need to have that SDK on your computer I would say.
To make sure it references, you'd expand your project in the "Solution Explorer" and then find References. Right click on that and add reference, then using one of the tabs browse and find the SDK. I don't know the details of how to point to it. But that would include one or more dll's which contain the SDK methods you might want to call. Not sure if you'd need the SDK though, probably not.
That's a pretty tough assignment for someone new to any programming language. Ouch.
