Yes, there is a new Linq CTP, but this isn't exciting. What is exciting is this post. The exciting thing about it is that I can now intermingle code & data freely. This is going to have some major reprecussions, I think. I can do it now, using LCG, but I don't know a lot of people that would like to do that on a day to day basis. This puts us in a whole different level.
One simple thing that this may mean is that I can build a smart cache that will take an expression tree, compile it to runnable code, check its in-memory objects using this code and if it is not found will use the expression tree to query a database. This is powerful.
The next bit of news that I would like to hear is a ship date, to tell you the truth.
