Questions, Lots of Questions

The announcement was posted to Scott Guthrie’s blog and announced simultaneously on the main Microsoft web site.  Developers quickly began posting impressions and questions, many many questions.

Christof Jans asked: “Will immediate mode graphics and hardware 3D features be cross-platform?”

Another developer, Bruno asked for a high precision timer to be included in release 5.0.  While Dan Devine lamented the 6 month wait for the release version.  Many developers were asking for Windows Phone 7 support and even further, cross-platform support down to the device level, most notably for Android.

Steven DeRoo fired several questions which were on more minds than his own:

“Will Silverlight have to conquer HMTL5? …. Which other OS will be supported? ….  Will Silverlight be the next ActiveX? ….  Should companies consider Silverlight …. in favor of HTML5?”

Hopefully as more information is released and the beta is released to the public, many of the questions will become answered.  The Silverlight 5 beta will be available sometime early in 2011 and more information will soon be available at the Microsoft Silverlight site.
