I know about LocalDbConnectionFactory but I'm interested why using SqlConnectionFactory with the string 

"Data Source=(localdb)\v11.0;Integrated Security=True; MultipleActiveResultSets=True"

causes System.Data.Entity.Core.ProviderIncompatibleException to be thrown.

SqlConnectionFactory is probably geared towards SQL Express and can't deal with LocalDB, which is why they added the LocalDbConnectionFactory.

Is there some reason you can't just use the LocalDbConnectionFactory?

  • No reason, just want to know why. I thought LocalDB is absolutely the same sql express. At least it's what I got from docs. – Pavel Voronin May 01 '14 at 05:54
  • They are not the same, from the SQL Server Express guys [blog](http://blogs.msdn.com/b/sqlexpress/archive/2011/07/12/introducing-localdb-a-better-sql-express.aspx) looks like Express will probably be going away in time. – Mikee May 01 '14 at 12:55
