Where is the best place to place business rules in a Silverlight MVVM RIA Services application?

Question

Where is the best place to place business rules in an RIA Silverlight application?

I thought that a domain service would be a good place, except that, apparently, only Data is passed to the client level. I don’t think ViewModel is a good idea, since we have to have business rules at the server level.

In common code? * .shared.cs? A.

Where do you post your business rules?

Answer 1

For RIA services, your business logic must be in a domain service.

Can you give an example of how this is a problem for you?
