dynamic data in .net 3.5 SP1 -- performance, multi-tier

[Ryan Liu]

Hi,

I am going to develop a new application, I found .net 3.5 SP1 comes with new
feature called dynamic data.

My question is :

1 How about the performance of that? Is it using lots of reflection etc so
slow down the application?

2 And is that against the idea of multi-tier separation?

That is dynamic only suitable for quick and dirty small application, or it
can also be used in serious business application?

Thanks a lot!
Ryan
