How can I re-attach an entity to a new DataContext? When I try to do this I get an exception thrown.
How can I keep entities cached beyond the lifetime of a single DataContext? I want to keep a collection of entities in a cache so that all subsequent requests can read from this cache instead of going back to the database each time.
Should I keep my DataContext in a static/global/shared variable?
Should I create a new DataContext in every business logic method?
How do I get default values from the database when inserting new entities?
