Syncing entities from two different data providers?

Question

This might be a duplicate but I couldn't find appropriate solution,

Server:

• SQL Server
• Entity Framework
• WCF Service

Client

• SQLite
• Entity Framework for SQLite
• WPF

Requirements

I've few common tables in the server and in the client with same table name and same column names.

My task is to delete the data from the client tables and copy the data from the server tables by calling it through my WPF application.

Possible Solutions

1. Using Microsoft's Sync framework (but data providers are different so, it may or may not work)
2. Using traditional approach (removing entity framework) & use Datasets instead.

Are there any better solutions to achieve this Sync functionality?
