(localDB) \ Projects or (localDB) \ v11.0

Question

I installed VS2012, SSME 2012 with localdb, and I found that I have 2 servers with which I can connect: (localDB) \ v11.0 and (localDB) \ Projects.

Which ones should I use to perform, what are they for?

Answer 1

This explains the difference and some issues to keep track of.

Not sure about the difference, but you should use

(LocalDB) \ v11.0

Answer 2

I know I'm late. But now I came across the same question and found the answer. I think I should share the Answer :

(localdb) \ Projects is an instance of LocalDB SQL Server Express that is used by default by SQL Server tools to host sandbox databases created for your database projects (* .sqlproj) to enable F5 deployment and debugging.

(localdb) \ v11.0 is a generic instance of SQL Server Express LocalDb that is created when LocalDB is installed and also used by other Visual Studio projects, such as ASP.NET projects.

Update

Starting with EntityFramework 5.0, SQL Server is by default your localdb \ vxx.x instance.
