There are two things, really that make it more complicated:

• Implementing INotifyPropertyChanged
• Commands

One thing you can do in Silverlight is use the "Property Weaver". It will do something similar to the [Binding] tag in Flex as it will automatically take public getter/setters and re-write them with the INPC pattern.

As for commands, wrapping methods in DelegateCommands proves to be a lot of plumbing. There are several approaches to this. I like a convention-based approach, where you declare a public method named Execute_Something and the command Something is automatically created for you to bind to. Here and Here.

Finally, binding in Flex is expression-based where as binding in Silverlight is purely declarative. I have some ideas for when we get C# v.Next and we might be able to do expression-based binding pretty easily.
