v4.3.12907.0-Beta2

• Status of the operation can now be reported to the Engine without throwing an exception. The IFile.WriteAsync(), IFolder.WriteAsync(), IFolder.CreateFileAsync() and IFolder.CreateFolderAsync() methods now provide a new IInSyncResultContext parameter parameter to explicitly set the in-sync status of the item. The resultContext parameter of the IFileSystemItem.MoveToCompletion() and IFileSystemItem.DeleteCompletion() methods now implement IInSyncResultContext interface.
• Placeholders.GetRootItem() method added.
• Deleted items processing in Engine.ProcessAsync() performance improved.
• New items were treated as existing by the Engine.ProcessAsync() method. The IFile.WriteAsync() method was called for new items. Now this bug is fixed.
• gRpc channel did not work if package is installed for more than one user on the same machine. Thumbnails and custom columns does not work in Windows Explorer. Now the gRpc channel is unique per user.
• PlaceholderItem.GetCustomData() method and IFileSystemItemMetadata.CustomData property are removed (replaced with PlaceholderItem.properties dictionary).
• IServerNotifications.MoveToAsync() returned false even if the file is successfully moved. Now this bug is fixed.
