New Post: DataFacade.GetData not working reliable

If you're using DataConnection, there's no need to call ThreadDataManager.EnsureInitialized().

Usage of DataFacade is not recommended, as it a more low level operation and, as for now, requires creating a thread data for it, as well as "data scope"

using(ThreadDataManager.EnsureInitialized) 
using(new DataScope(publicationScope, cultureInfo) {
  ....
}
