http://blogs.msdn.com/tims/archive/2004/11/19/267048.aspxOne of the areas that I've seen cause a bit of confusion in the newsgroups and on blogs is the difference between three technologies that will ship with Longhorn: Avalon, XAML and Aero. I wanted to address this quickly in the hope that it helps us allen-USCommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/tims/archive/2004/11/19/267048.aspx#267060Fri, 19 Nov 2004 23:52:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:267060Gokul ThirumalaiInteresting. Thanks for the clarification. <br> <br>But as of today, what's shipping with longhorn and what's not?http://blogs.msdn.com/tims/archive/2004/11/19/267048.aspx#267062Fri, 19 Nov 2004 23:56:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:267062Tim SneathLonghorn will include all three of the above.http://blogs.msdn.com/tims/archive/2004/11/19/267048.aspx#267071Sat, 20 Nov 2004 03:08:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:267071JD on MXNew Avalon version: If you've got an MSDN subscription, then there's a new &quot;Community Technology Preview&quot; version available.

If I add a control that I've created myself, the schema is extended. In other words, the schema becomes equal to the full universe of valid XML syntax. I don't know I've explained that very well, but perhaps that makes sense to you. Thanks for the question, anyway!http://blogs.msdn.com/tims/archive/2004/11/19/267048.aspx#267236Sat, 20 Nov 2004 18:02:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:267236Jason HaleyLatest version of Avalon ready for MSDN subscribershttp://blogs.msdn.com/tims/archive/2004/11/19/267048.aspx#268419Tue, 23 Nov 2004 14:32:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:268419ISlavoF.Save()http://blogs.msdn.com/tims/archive/2004/11/19/267048.aspx#665295Fri, 14 Jul 2006 08:08:50 GMT91d46819-8472-40ad-a661-2c78acb4018c:665295StoneZone » Avalon, XAML???Aero?????????PingBack from <a rel="nofollow" target="_new" href="http://blog.stonezone.com.cn/archives/avalon-xaml%e5%92%8caero%e7%9a%84%e5%8c%ba%e5%88%ab">http://blog.stonezone.com.cn/archives/avalon-xaml%e5%92%8caero%e7%9a%84%e5%8c%ba%e5%88%ab</a>
