Differences between Silverlight 2.0 and 3.0

I am migrating a graphics intensive Silverlight application from 2.0 to 3.0 开发者_如何学编程and at the same time evaluating if there are new features in Silverlight it could expose. What features would you suggest are the most important new ones in Silverlight 3.0?

I have gone over the Silverlight Wikipedia article which suggested the following are the most important new features in 3.0:

• New controls
• New audio and video decoding (AAC and H.246)
• Perspective 3D
• Element-to-element binding
• Limited filesystem access
• Installation for offline usage

What other changes / new features are notable as an application developer?

There's a pretty good, fairly comprehensive summary of the new features here:

WriteableBitmap is one of the most notable 3.0 features if you're working with images.
