Microsoft recently released vs 2012 beta, while lightswitch also released V2 beta. According to the official statement, lightswitch and vs platform will be released later, but only available in professional versions or later.
During the holiday, I went to the next test and found that the version of LS introduced a new basic logic layer technology, replacing the original WCF Ria with the WCF dataservice (WCF data service ). Since the WCF Data Service uses Microsoft's open protocol odata, odata will be used in any technology used by the client for server access in the future, so that ls will have a better prospect in the future.
At present, although the client still uses the Silverlight technology, it is of course the option to introduce it directly after the metro technology is mature. It can solve the problem of slow client running speed when LS is currently running! ··!
