Yesterday, Liam Cavanagh in his blog has announced Sync Framework v.2 CTP.
In new version of Sync Framework beside all, has been simplified proccess of creation of own providers for Sync Framework. In my opinion, it’s very important part of this technology, because it’s provide reduce complexity of sync providers development and allow to developers for create own providers.
P.S. BTW, may be you already use Sync Framework in your real projects?
