Jason Beres from Infragistics in Boston, Mass was the guest speaker at Ottawa dot net community Events speaking about Silverlight. Silverlight was just released on Sep 5.

We have been testing CTP's for WPF/E, now called Silverlight, since 0.8 release. There have been some subtle changes in the interface definitions. In upgrading our Silverlight projects from 0.9 to 1.0 (see http://www.trackerrealm.com/blogs/WPFEControls/images.htm), we noticed the following changes:

• Javascript is no longer a part of the Xaml file. Events have moved from the Xaml file to a "code behind"Microsoft Javascript file using an AddEventListener method.
• I refer to it as a Microsoft Javascript file, because it does not conform to the standard JS file format. Rather, Microsoft have created a Javascript object model.
• A number of Xaml Control properties are gone. (not deprecated, but gone)

Meanwhile, back to Jason - fantastic presenter and presentation. Jason discussed Silverlight 1.0 and 1.1. He juggled back and forth between the formal release and the CTP highlighting differences. Key points:

• Silverlight is Microsoft's competitor to Adobe Flash. (great graphics and animation.)
• Silverlight is a cross-browser plug-in.
• Silverlight is Xaml-based.
• Silverlight is a stand-alone product, ie. not dependent on .net. (Microsoft are integrating base classes from .net)
• Silverlight 1.0 release is 4.6 MB. (expect Silverlight 1.1 release to be about 7 MB)
• Silverlight language for the code behind file in 1.0 is Javascript
• Silverlight language for the code behind file in 1.1 is C# and VB.net
