Before
You Start…One
of the first things you’ll notice is the streamlined Visual Studio 2010 SDK.The
SDK is now just 10 MB in size, instead of the 100 MB it used to be. We accomplished this by moving the
documentation
and samples
online, which allows us to provide and update content continuously. The SDK’s install time has also gone
from 20 minutes to just over a minute.
