title: multiple localdb instances in separate files
body: <p>I'm trying to run the same project multiple times on the same machine, and each instance needs it's own distinct localdb instances stored in it's own personal mdf file (this might sound strange but I have a reason for doing this). Currently I'm attempting to use the same connection string name with different files, but this doesn't work. Here's an example connection string:</p>
  
  <pre><code>&lt;add name="dbContext"
       connectionString="Data Source=(LocalDb)\v11.0;AttachDbFileName=|DataDirectory|\db-&lt;string-unique-to-project-instance-1&gt;.mdf;Initial Catalog=dbContext;Persist Security Info=True;Trusted_Connection=False;" 
       providerName="System.Data.SqlClient" /&gt;
  </code></pre>
  
  <p>However upon running the project the database file is not created as expected, even though interrogation of the connection string that's loaded into memory shows the correct value.</p>
  
  <p>What connection string allows for multiple localdb instances / is there something else I need to do?</p>
  
  <p>Note: I've also tried using a distinct connection string name to no avail.</p>
