I downloaded a sample SQLExpressProviderSample from http://code.msdn.microsoft.com/sync/Release/ProjectReleases.aspx?ReleaseId=1200. (SQL Express - Client Synchronization Sample (C# v2.0 CTP1) )
In the sample database, there are only 5 columns in table orders. If orders table in my project has 20 columns, how to code to sync each column?
I download another sample from http://www.codeproject.com/KB/smart/takedataoffline.aspx, it needs to add code for columns.
