Have a look at Avalon ….
By popular demand, the Avalon team has provided the November 2004 Avalon Community Technology Preview for the general public.? In addition, the team has provided a batch file to enable the Avalon project item templates for use in the beta of Visual Studio 2005 Express Edition, which is also freely available to the general public.
This combination enables folks without an MSDN Subscription to try out Avalon with Visual Studio 2005 without an MSDN Subscription.
Don’t be shy about giving feedback on these bits now that you’ve got ’em. The Avalon team is standing by in the Avalon newsgroup to answer your questions and take your suggestions.
