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

Question

User-112360272 posted

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?

And I just give it a try, seems by default, it use db column name as lable, it is not acceptable. Can I use more user friendly lable for controls, e.g. have space in it, like "Project Name"? 

I will do more testing. But quick answer is appreciated.

Thanks a lot!
Ryan

There is a small performance hit I read around 10% and I think that is mostly Linq to SQL of Entity Framework

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

Out of the box there is nothing for idea of multi-tier separation, although there are some samples in Dynamic Data Futures sample on Codeplex here: DynamicDataFutures0716.zip

can also be used in serious business application?

Not at all I'm working on a larg admin tool for a major web app with lots off Dynamic Data customization.

And I just give it a try, seems by default, it use db column name as lable, it is not acceptable. Can I use more user friendly lable for controls, e.g. have space in it, like "Project Name"?

You can change all that via metadata have a look at some of the intro videos here on ASP.Net: ASP.NET in .NET 3.5 SP1 see the ASP.NET Dynamic Data section at the top [:D]
