Rocky Lhotka recently announced a pre-release drop for CSLA Light (the less filling version of CSLA 3.6). Silverlight raises special problems for creating tiered applications. CSLA Light tries to fill this problem domain by providing a framework for building bindable objects that know how to interact with Silverlight. This is the sort of solution that will allow us to do more than simply build cool games with Silverlight, since the real promise of Silverlight is the ability to write business applications that are also RIA’s.
One of the few alternatives to CSLA Light that I’ve seen is Shawn Wildermuth’s work integrating Astoria with Silverlight. I’m keeping an eye on both of these technologies to see how line-of-business Silverlight applications will shape up over the next year.
