Spent the afternoon at the MIND meeting. The main talk of the day was about Paladin, a homegrown .NET object persistence framework, presented by Microsoft MVP and the author herself, Serena Yeoh.
Paladin offers O/R mapping, enterprise services transactional support, forward engineering, stored proc support, and the codegen wizard looks pretty sophisticated. Here's a goody: It's free!
Broaching on the subject of object persistence frameworks, it's too bad that Microsoft's ObjectSpaces is still not ready for prime time. It won't be ready till the release of WinFS. The bad news is that WinFS won't even make it into the initial release of Longhorn. :-( Not surprisingly, we're seeing a trend of such third-party/homegrown frameworks cropping up to fill the void. Some are free and some not.
Prior to watching Paladin in action today, WilsonORMapper by Paul Wilson is one such framework that I've keenly looked at so far -- primarily because the APIs resemble those of ObjectSpaces. It offers support for a wide range of databases and uses simple XML-file-based mapping configuration (instead of custom attributes).
