Answer 1

The clue is Data Source=(localdb)\Projects;

EF 6.0.1 puts the databases here: Data Source=(localdb)\v11.0;

Data Source=(localdb)\v11.0;
Integrated Security=True;Connect Timeout=15;
Encrypt=False;TrustServerCertificate=False

in SSDT in vs2012/vs2013 [View, SQL Server Object Explorer],
right-click the node "SQL Server", then click "Add SQL Server..."

Type "(localdb)\v11.0" for the server name and click Connect.

You should now see both "(localdb)\v11.0" and "(localdb)\Projects" in SQL Server Object Explorer.

Your code first databases will be in the Databases node under "(localdb)\v11.0".

FWIW, i have zero idea why Microsoft made this annoying change.
