The ADO NET Team has been cranking out fab content on their blog. Brian Dawson just wrote a post all about Object Services.
In trying to sort out all of the options that we now have with Entity Framework and LINQ, I’m always happy to see a list like this. But go read the whole post so nothing is out of context
What can you do with Object Services?
Here’s a bullet list of some of the normal operations which object services can provide:
· Query using LINQ or Entity SQL
· State Management – change tracking with events
· Lazy loading
· Navigating relationships
More features of Object Services allow for data conflicts resolution. For example, Object Services supports:
· Optimistic concurrency
· Identity resolution – keeping on copy of the object even from several different queries
· Refreshing data with overwrite options (ie: server wins or client wins)
