How does dosync synchronize data between local and remote databases?
At each sync, DoSync will create the tracking tables in the local database and the base and tracking tables in the remote database as needed, then synchronize the data between the two databases. In Figure 2, the SyncSQL2008_Standard_Express_Compact35 project is a C# project.
What causes a table to be synchronized with the master database?
Each table to be synchronized must have a unique primary key for each row. New records must generate primary key values that are unique across all nodes in the master database. If the schema for all nodes is exactly the same, the commonly used Identity Seed integer primary keys can cause problems.
What does data source mean in the Microsoft Sync Framework?
A data source refers to the location where the data to be synced is stored. A data source can be any of the following: Sync Framework stores state and changes information about a data store in metadata. This metadata, in turn, can reside in a flat file, a database, or within the data source being synchronized.
How does the Microsoft Sync Framework work for offline use?
Despite the availability of wireless and cellular networks, many applications must support remote office or offline data collection and presentation services. Microsoft Sync Framework is a highly flexible framework for synchronizing files and data between a client and a master data store.
Can the Sync Framework be used with ADO.NET?

How to create custom sync providers with the Sync Framework?
The Sync Framework engine makes this entire synchronization process easy. The Sync Framework provides support for three default providers for database, file system, and source sync: You can also extend the Sync Framework to create your own custom sync provider for exchanging information between devices and applications.
How to implement data synchronization in Microsoft SQL Server?
Implementing and maintaining data synchronization is such a time-consuming process that it can be a full-time job in itself. We can implement the architecture for data synchronization tasks manually, possibly using the Microsoft Sync Framework, or we can benefit from solutions already built into the tools to administer Microsoft SQL Server.
Who are the providers of the Sync Framework?
There are several providers in the Sync Framework that support many common data sources. The following are the included providers, Database Synchronization Providers: Synchronization for ADO.NET-enabled data sources. File Synchronization Provider: Synchronization of files and folders.
