Re: Dynamic ORM?
I use a self created ORM solution where the DAL DLL does not need changing between projects as it maps the entity object to the appropriate stored proc based on custom class attributes. A custom built code gen builds the entities and stored procs (as well as WPF MVVM View & VM, ASP.NET Forms & usercontrols) based on the db structure, so any changes to the database are easily updated in the stored proc, and then in the entity classes. Thinking of making it available for sale, hopefully sometime this year... Ideas are far outweighing my time availability at this point.

Re: Dynamic ORM?
I've heard of a few projects that needed to do something like this (mingle is one that comes to mind) where the structure of your entities can be modified at runtime. It gets really complicated very quickly - especially in getting the implementation to perform adequately. This seems a better fit for a non relational database such as mongodb, ravendb, couchdb etc. if that's an available option.

Performance nat an issue.. Test harness proves its quicker than linq for same query (single and multi record). it also returns multi resultsets with good speed too. 10 result sets from 1 stored proc in 20 millisecs.
