What information has been released regarding the .NET Framework 4.0?

Question

As Microsoft seems to have started their trickle feed of information regarding .NET 4.0, I thought I'd ask the question as I'm sure there's more out there than I've spotted!

What information has been released regarding the .NET Framework 4.0?

Answer 1

InfoQ has some good information, but doesn't go into the details.

• Type embedding
• Dynamic types in C#
• Optional parameters in C#
• Type covariance and contravariance

Microsoft have an information page for downloading the Visual Studio 2010 and .Net 4 CTP here.

Answer 2

http://news.google.com/news?hl=en&ned=us&q=net+Framework+4.0&btnG=Search+News is a good place to start

Answer 3

ComputerWorld Australia just ran an excellent interview with Anders Hejlsberg , in which he talks a little bit about what's coming in C# 4.0.

Answer 4

This video on Channel9 provided some interesting information on the next version of C#. Obviously, some of these changes will have to be backed into the CLR...

(Video is of Anders etal talking about 4.0 in the room C# was born)

Answer 5

It's mostly marketing "spiel", but there's a post on Steven Martin's blog discussing some of the new things to come in WF/WCF.
