Guys, I am looking at writing a blog post on some of the new features. Of these, I would like to cover:
- the new LINQ DML stuff - the ability to query unloaded collections - creating sessions with properties - async methods - changes related to ambient transactions Anything else noteworthy? When is 5.1 expected? Thanks!
