We've been working on some very cool things here at ro, one of which is:

What's shown here is a Silverlight 2.0 beta2 object inside Internet Explorer that fetches data using a LINQ query to a DA server using RO using DA-SQL (more on that will follow in a blog posting from Marc) fetched and sent back to the server, all running asynchronously. The grid used is the excellent AgDataGrid from DevExpress.

New in the next DA/RO for .NET will be running requests asynchronously, this will make it possible to run a RO or DA request non-blocking and get a threaded callback once the data (or exception) is ready, this will even work with DA/LINQ. Another new feature is Silverlight support in RO and DA, and DA-SQL which will be covered in the following blog posts.
