A guy on my team has been playing around with an API usage frequency tool… the idea is to gather data on the most used APIs in the framework. What he does is scan the IL for all calls to methods and sum the number of calls for each API defined in the BCL.
He recently ran this tool over a current build of Longhorn which contains a large managed code base. Can you name any of the methods in the top 10? Think about it a bit, it might be harder than you first think… I’ll post a hint tomorrow if folks are not in the right track.
