here is the situation I have a .Net desktop application which stores it's data on local file system (using sqllite). And there is the master database on a remote server which. The desktop application needs to synchronize data to the master database when ever there is a dial up connection to a specif server or when ever there is an internet connection. Is there a simple library for synchronizing/replicating data for occasionally connected system to/from a master database using dailu-up or internet connection?
