I just noticed that there has been a new release candidate published for the Avalon and Indigo beta 1. This package will work correctly with .NET Framework 2.0 beta 2 and will integrate into the IDE in VS 2005 beta 2. This will eliminate the problems described in this previous blog post. You can download this build by clicking here. There is also a link on this page to an ISO image for an SDK that will provide documentation, samples and tools.
