Moved some VS 2010 over to VS 2012 running on a Window7 pc. When I go to open one of the solutions in VS 2012 I get a message to the effect that the project "requires SQL Server Express which is not installed on this computer. The recomended database engine for visual studio 2012 is SQL Server LocalDB Express. To upgrade the project database SQL Server LocalDB Express double click the database file and follow the instructions..." . My question is what database file should I double click? I look through my project and don't see any SQL Server database files.
Could someone kindly show me what I should be doing to upgrade to SQL Server LocalDB Express? If I'm missing something obvious please excuse I'm a bit of a newbie to VS. Thanks much in advance for any help, Roscoe
