Core Data what would be the Windows Phone equivalent -

I was looking for any equivalent library or framework in Windows Cell SDK 7.5 or 8, which has similarities to the iOS core data.

Seeing the stack overflow I got this question: But this problem does not solve much.

Is there any alternative to core data on Windows Phone SDK?

Unfortunately there is no such library / framework, but the nearest relative of core data in WP8 is Linq to SQL but Of course, linux to SQL and core data are two different things, and their objectives are different too.
