Posting my code:

 They potentially lock the customer table because concurrent edits are not supported by the business level or the underlying data model.  
 Given this restriction, there is no way around the problem.  
 They allow synchronous method to call Asynchronously so that you do not have to block until the method is completed, but that does not mean that you can be in the editing of two customers at the same time. Still you can do other things when editing is complete.
