Information about ADO. NET Entity Framework

Today, I visited the blog of the ADO. NET Entity Framework Team. I am interested in this project because I also write Orm. :) Of course, that grade is not a level.
I don't know how many pigeons I put in this project. I still remember the objectspace stuff. Now it's in beta 3, and I 've even published it in LINQ. He can't keep it up. (Winfs in Vista, I guess it's the same thing, so winfs has to put it .)
Well, let's get down to the truth. What are there?
First, there are articles published in beta 3 (not News ).
-Performance Improvement;
-Provide necessary events for business logic support;
-Improved query and compiled LINQ support. The toreacestring () method is provided for debugging;
-Better support for other databases;

About the designer:

Of course, there are a lot of tutorials and so on.

Of course, I am most interested in this:

He said above that. Net FW 2.0 SP1 increased the sqlreader read performance from 14855 to 18100, not a general performance improvement.
