Glenn Block has announced that the Prism RC has dropped. You can get it from here.
Prism is the next generation in composite application guidance. If you are building clients for the desktop, this framework can help you tremendously. It was built to be agnostic of any frameworks. So you can chose your own IOC container, your own logger etc. For those of us who did not like CAB for some of these reasons this looks to be the way to go.
I got the chance to chat with Glenn at the 'Ask the Experts' series given at Tech-Ed this year and was impressed with all that they had done to make it so that shops could continue to use the application services that they are used to using. I am sure once I get into it, there will be something I don't like, but it sure beats writing it from the ground up.
Go out and get it....and let me know what you think.
