Today's simple Longhorn dev trick?
Reference the sdk links in code comments, for example:
//timeline sample: ms-help://MS.LHSDK.1033/LHSDK/lhsdk/Samples/graphicsmm/timing/restarttimelines_csharp/./Source/default.htm
Thus you can click the links in the code, and get a convenient browser window within VS to view sample code.
