http://blogs.msdn.com/b/cyrusn/archive/2005/04/18/409413.aspxKevin takes me to task over my poor design skills. Take a look over: here In my defense, i was going for simple and understandable. Unforunately it turned out in a certain scenario there was also an unfortunate perf impact. Now, i have drasticallyen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/cyrusn/archive/2005/04/18/409413.aspx#409728Tue, 19 Apr 2005 20:50:44 GMT91d46819-8472-40ad-a661-2c78acb4018c:409728Sean ChaseCyrus - No, thank *YOU*. :-) <br> <br>*sigh* <br> <br>At the same time I'm left frustrated having to wait until Sept for the RTM for all of this great stuff that I need now! VSS now works over HTTP(S), ASP.NET doesn't require IIS for development, refactoring, nullable types, better intellisense, generics...stop me any time...I want it now. Gimme gimme gimme!!! :-)<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=409728" width="1" height="1">http://blogs.msdn.com/b/cyrusn/archive/2005/04/18/409413.aspx#409655Tue, 19 Apr 2005 18:08:42 GMT91d46819-8472-40ad-a661-2c78acb4018c:409655CyrusNRonO: &quot;Can't you prototype the design changes and run a set of side-by-side regressions over both versions?&quot; <br> <br>Yes. But i can guarantee that it won't catch everything. Things will regress without question, and our ability to find out about those regressions is severely limited because of the very little time that's left.<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=409655" width="1" height="1">http://blogs.msdn.com/b/cyrusn/archive/2005/04/18/409413.aspx#409654Tue, 19 Apr 2005 18:07:01 GMT91d46819-8472-40ad-a661-2c78acb4018c:409654CyrusNThanks Sean!

Nice job you guys!!!<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=409446" width="1" height="1">
