Getting Sql Server Data Tools to work with Visual Studio 2012 Express Release Candidate

I’m struggling with migrating to Visual Studio 2012 Express Edition to handle a project that includes a database project with a .dbproj extension. This blog http://visualstudiomagazine.com/blogs/data-driver/2012/06/getting-visual-studio-2012-and-ssdt-to-work-together.aspx gives the impression that with a bit of work this is all basically manageable.

LINQDataSource – Query Multiple Tables?

I have a database and I’ve created a DBML Linq-to-SQL file to represent this database. I’ve created a new aspx page and dropped a linqdatasource and a formview control onto it. When I configure the linqdatasource it gives me the choice only to select * from one table…but I want to pull from multiple tables. e.g. I have tables like simple_person, simple_address, simple_phone, and I want to pull from all of them. How can I accomplish this?
