We have just posted a new Sync Framework sample for devices to our code gallery entitled "Sync101 - (Windows Mobile) Device Synchronization".
This C# sample is meant to show how to use Microsoft Sync Framework on smart device such as Windows Mobile and to illustrate the "remote change application" (RCA) pattern over a web service (between a desktop PC and a smart device).
The current release of "Microsoft Sync Framework for Devices" does not contain the Metadata Store service. Because of this the provider on a device needs to implement the necessary metadata management functions in a type named "MyProviderMetadata". This sample shows how this can be accomplished. Using this sample the provider on desktop will still uses the Metadata Store for an easy approach.
