Incorporating a SDK in a Program

Question

Hi

Im working on a project that needs Pastel's SDK's reference.
I have added all the references needed.

Now I need to make use of it...

What i have so far.

using PasSDK; //this is at the top of my Form.cs
PasSDK.PastelPartnerSDK SDK; //this is in the namespace (i think it's wrong)

in Visual Basic it does this:
Dim SDK As New PasSDK.PastelPartnerSDK

I'm sure that this is a very simple thing...
Please assist.

Thanks
