RIA Services Roadmap
If you’ve tried out RIA Services for integrating Silverlight with multi-tier distributed applications, you might be interested in their recent roadmap update for getting to a first release.
The existing May preview and samples will be followed by a July preview that tries to shake out the remaining major changes.
The beta is at PDC this year.
The first release is in 2010 using .Net 4.0 as a prerequisite.
Dinesh Kulkarni has more details in the complete roadmap update.
