title: Microsoft Sync Framework Alternatives
body: <p>What do you use for data synchronization?</p>
  
  <p>I have been working with Microsoft Sync Framework for a couple months now and I'm not sure if I like it. The concept is great but I've had trouble with remote sync. There is no remote file sync provider, but I did manage to write one with a lot of trouble. There is also no way to show progress that I am aware of on ADO.NET sync services.</p>
  
  <p>I'm coming up with an error when two clients try to sync at the same time. "The metadata store is already in use." After all the sleepless nights trying to get a remote file sync provider working and now this error, I am now in search of alternatives.</p>
  
  <p>Is there any better alternatives to MSF?</p>
  
  <p>Does anyone know of any open source frameworks or samples?</p>
