Please help me to connect my forms I created in Visual Studio 2010 to Sql server 2012.

As read on: Microsoft Connect

"It looks like you're trying to use VS2010 Database Projects, which can't target SQL Server 2012 and have been replaced by SSDT. Please download SSDT at the following location, then make sure to navigate to the SQL Server node when creating a new project. There is only one project type for targeting SQL Server 2005, 2008, 2008 R2 and 2012 (target is specified in project properties)."
