The Avalon + Indigo May CTP (aka the “Beta 1 RC”) is now live on microsoft.com and ready for your consumption. You’ll also want to install Visual Studio Beta 2 before you start playing.
Drew Marsh has already started a change log to help those of you who plan to port your projects from the March CTP to this release.
And I will point you to other resources as they materialize…
Avalon and Indigo go so well together!
