Just come off the phone chatting to Richard Costall, who besides his real job, runs the rather splendid Next Generation User Group. He mentioned he had posted up a very recent interview with Scott Guthrie that touched on Orcas, Atlas (now ASP.NET AJAX) and WPF Everywhere. In the spirit of "that would make a nice change" approach to a work day I read the transcript. The bit that stuck out for me (and arguable I should know this stuff - but I don't!) was:
This is great news - so many early adopters we worked with on Visual Studio 2005 asked us for this capability - great to see we listened.
从上面的内容来看，很明显.NET Framework的基础（最典型的就是CLR）还是目前的2.0，离所谓的.NET Framework 4.0还比较远，不过听在ATC的朋友说，4.0也已经在筹备之中了（这可能只是谣传，不足为信，仅供参考）？所谓的ASP.NET 3.0还不见踪影，不知道这会事怎么样。倒是C#3.0和ADO.NET 3.0的消息不断，但这基本上还是会以组件的形式提供给开发者。CLR不变，其实变化都不会太大。呵呵，有时候也还是不要升级的太快为好。.NET Framework 3.0的几个组件我还没有搞清楚呢。:)
