LocalDB: change SQL Server default location

Question

I wonder if it is possible to change default location of (LocalDB). When you create it with SqlLocalDB.exe default location is

C:\Users\userId\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\MyDB

And I believe this path is used in (LocalDB) in connection strings (auto generated by creator of *.dbml files):

<connectionStrings>
    <add name="MyApp.Properties.Settings.MyConnectionString"
         connectionString="Data Source=**(LocalDB)**\MyDB;Initial Catalog=sthDB;Integrated Security=True"
         providerName="System.Data.SqlClient" />
</connectionStrings>

Answer 1

You can't change the default, but you can change it for every database you create:

create database foo on (name='foo', filename='c:\DBs\foo.mdf')
