I have SQL Server express 2012 and webmatrix 3 but would like to upgrade my SQL Server Express to 2014.
The web platform installer does not seem to include SQl Server 2014 ?
Is it a good idea to upgrade to express 2014 when working with webmatrix and web pages ?
You should ask questions about Web Platform Installer over here: http://forums.iis.net/1155.aspx/1?Web+Platform+Installer.
There’s no reason why you cannot use SQL Server 2014 or indeed any other database with Web Pages sites. You can download SQL Server Express 2014 here: http://www.microsoft.com/en-gb/download/details.aspx?id=42299
