I have seen many nice things coming up for ASP.NET 4 and Silverlight 3. The best thing i've seen is the DomainDataSource where one can create a nice separation of Business and Data Layers and present the BL in both SL and ASP.NET.
These examples make heavy use of IQuerable.
My question to my fellow developers is:
How can I implement IQuearable using nHibernate? Is there a nHibernate2Linq framework??
