synchronize two SQL CE 4.0 databases
===

How to synchronize two SQL CE 4.0 databases? I'm using version 4.0 because I want to use the code first approach. As it turned out SQL CE 4.0 does not support MS Sync framework, and SQL CE 3.5 supports MS Sync but does not support  full code first approach. (No Database Creation). I would like to use at least EF database first. How can I do in this situation? Abandon the code first and switch to SQL CE 3.5? Use SQLLite or other compact database like ms access. Maybe write my own synchronization using a TimeStamp for each row.
