Several of you have asked for a more complete list of the features that are new or improved in Silverlight 5, especially those new to the RC. Here is my mostly complete list of major features. I haven't included the tons of fixes and improvements, but maintained a focus on major features. (I say "mostly complete" so I have an out when I later realize I forgot something.)

  • ICustomTypeProvider (see Alexandra Rusina's post)
  • Custom Markup Extensions

  • Improved Graphics Stack
  • 3D Render targets (new since beta)
  • XNA 3D built-in effects (new since beta)

Productivity and Performance

  • Network Latency Improvements
  • Databinding Debugging

Controls

Other

Why weren't these all in the initial list?

My initial list only had a few key features listed. Some, such as Tasks and Covariance/Contravariance made it into Silverlight without me realizing it. For the most part, I got the feature list by checking with the product team and by trolling our specs repository.

So how does stuff make it in without it being on a master Silverlight list? That's easy. Many teams at Microsoft contribute to Silverlight either directly, or through other things such as the core CLR, framework, and C# language. Since Silverlight shares much of that code, cool and exciting features make it in without showing up in a Silverlight feature list. A great example of this is Tasks from TPL. The right people did know those features made it in (people actually writing code, the testers etc.), I just hadn't noticed it. It's not a conspiracy to keep the TPL folks down, trust me :)

Many of these features are documented on http://silverlight.net/learnvia an increasing number of tutorials.

In addition to that, if you're looking for a one-stop shop for learning Silverlight 5, consider my book Silverlight 5 in Action, to be released in print near the end of this year. It's currently in MEAP, with purchasers able to download chapters as I make them available.
