I have not taken the time to actually play with SL yet. But I have been watching the mix sessions and are very excited about what I see. However, from what I can gather, there are a few things missing. It seems important to get this news out soon, so Microsoft can start getting some customer feedback.

For starters, there is no combobox, but I must say that this really isn't a big problem. It might even be included in the final bits, or somebody will write one for sure. No biggy.

However, Karen's video highlights some shortcomings of styling: they are write once, no application theme style like we are used to and you can not use 'based on'. That is going to be awful to say the least!

Josh Twist has an excellent post up here, where he notices the missing elementname and relativesource bindings. He doesn't use the relativesource bindings much, but I can tell you, I've had to use them to enable some great scenario's. Not having them will limit me greatly (more then missing the elementname binding).

Finally, Rob Eisenberg triggered me to write this post, mainly to point to his post here. It's a great writeup of what he is missing. It appears there are not triggers around anymore. I had already noticed that SL is coming up with a new scheme for control template authors to define the 'states' and 'elements' that need to be implemented by a template author. However great that may be, they appear to have substituted this for the trigger functionality. I can tell you, that is just terrible. Triggers are a very important part of a wpf application, and like Rob, I would implore Microsoft to reconsider this.
He also notes there is no concept of the ambient datacontext anymore. wow.. that hurts. No longer parameter-less ctors for UIElement and Frameworkelement (so, you can only inherit from Control easily) and to me one of the most important features missing: no Commands!! That means we are in a world of pain.

I must say, this has diminished my expectations of Silverlight a little bit. I really hope some of these issues are fixed before going live, because they have proven so useful in WPF.

Also, no DataContextChanged event as far as I can tell...

PostSharp 1.1 already targets Silverlight 2.0, if it can comfort someone...
