How do I copy SQL Server 2012 database to localdb instance?

I had the same problem. What eventually did work was this:

1. Trying to restore the database (getting the error in the OP)
2. Detaching the database
3. Reattaching the database

What happened in the last step was that SSDT performed an upgrade of the data files, that apparently was in an older format. When that was finished, the database started working without any problem!
