Interested in learning more about developing Silverlight 1.0 applications? There's a lot of great info on the http://www.silverlight.net Website, but Wrox is also releasing a new book titled Silverlight 1.0 that will be out in October.
I haven't had a chance to read it yet, but knowing Ambrose and Devin my bet is that it's very good. I'll add more info once I receive my copy. It looks like everything is in color which should be really nice.
