We are now announcing the availability of v1.0 Service Pack 1 of Sync Services for ADO.NET on Devices (Windows Mobile).

“Microsoft Synchronization Services for ADO.NET 1.0 provides the ability to synchronize data from disparate sources. Rather than simply replicating a database and its schema, the Synchronization Services application programming interface (API) provides a set of components to synchronize data between data services and a local store. Applications are increasingly used on mobile clients, such as laptops and devices that do not have a consistent or reliable network connection to a central server. It is crucial for these applications to work against a local copy of data on the client”.

 

“Equally important is the need to synchronize the local copy of the data with a central server when a network connection is available. The Synchronization Services API, which is modeled after the ADO.NET data access APIs, gives you an intuitive way to synchronize data. It makes building applications for occasionally connected environments a logical extension of building applications where you can count on a consistent network connection”.

A few days ago, a number of people from the Sync Framework engineering team were interviewed by Charles Torre (from Channel 9). He shot a 1 hour video interview where we explained how the Microsoft Sync Framework works internally, some key concepts that developers need to take care of when creating new providers and how the Sync Framework team is focusing on both managed and native developer solutions.

The video can be viewed at: http://channel9.msdn.com/posts/Charles/Inside-the-Microsoft-Sync-Framework/ or downloaded directly in the following formats:

We have a couple more synchronization samples for you to take a look at.  These C# samples are based on Sync101 which is a sample template that allows us to show specific concepts relating to Sync Framework.  All of these samples have been updated to work with the latest v 1.0 release of Sync Framework SDK .

I am particularly excited about the remote change application sample (RCA) as it has been a common request to understand how to integrate Sync Framework with technologies like WCF and enable a service to manage the server provider componets of the Sync Framework.  

Each of the samples use the the SQL MetadataStore store for the metadata information for each replica database. This greatly simplifies the logic required to implement data synchronization between data stores. In these samples three in memory data stores are used to show how data collaboration can be accomplished and how the Sync Framework helps to minimize P2P complexities such as data conflicts / resolution and data deletions.
