[Help] Cloud Toolkit

Hello I have CloudToolkitN6.dll but I don't know how to use it can anyone tell me how to use it?

I already add that .dll file in my Project Reference but nothings change.....

did you expect for it to magically work?
i googled the name, clicked the first link, clicked "Files" then saw this: [Only registered and activated users can see links. Click Here To Register...]

maybe you could try something like this next time?
refer to "Example Programs"
