Entity framework June 2011 CTP questions

Supposedly this 开发者_运维百科release includes 2 features I'm interested in.

1. Enums support
2. Model can be broken into multiple files.

I don't want to install it because of issues people report, so I will ask questins here :)

1. Is there any wild guess when we get production-ready version of this stuff?
2. My issue with EF right now is that it get's really slow after 100+ tables. Do I understand correctly that new feature with multiple diagrams will help with scalability?

1. Its in EF version 4.1

2. Code first method drops the EDMX designer all together, its all in code using classes, and if a slow designer is a a big thing for you, code first method is definitely for you.
