is 2012 much more restrictive than 2010, or 2010 was also like that?
I read that if VS 2012 opens an older version of database file of sql server, in order to do development, that database file has to be converted into sql 2012 format. (the the db files cant be accessed by the older versions of sql server).
was VS 2010 also this way? or 2012 is a big shift in compatability issues?
