title: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. The specified LocalDB instance does not exist
body: <p><strong>EDIT:</strong> <em>One important detail that I original left out (because I didn't know it was important) is that we were running these sites in full IIS, not from IIS Express.</em></p>

  <p>We're trying to setup local dev environments for Kentico CMS that will add our local machines to our current synchronization chain of Dev --> Staging --> Prod (so we'll wind up with Locals --> Dev --> Staging --> Prod).</p>
  
  <p>We copied our Dev DB to our local machines onto the (localdb)\v11.0 instance of SQL Server, but we're running into an issue on everyone's computers except mine.  </p>
  
  <p>Here's the error we're getting:</p>
  
  <blockquote>
    <p>The application could not connect to the database, please check the
    connection string in the web.config file and SQL server availability.</p>
    
    <p>Original error:</p>
    
    <p>A network-related or instance-specific error occurred while
    establishing a connection to SQL Server. The server was not found or
    was not accessible. Verify that the instance name is correct and that
    SQL Server is configured to allow remote connections. (provider: SQL
    Network Interfaces, error: 50 - Local Database Runtime error occurred.
    The specified LocalDB instance does not exist. )</p>
  </blockquote>
  
  <p>I've tried a ton of suggestions from other SO answers and other websites to figure out why we're getting this error (and why it's not happening on my machine), but no luck.  We can connect to (localdb)\v11.0 in SSMS but we cannot connect to it through VS (same error).  Also, when we open Sql Server Config Manager, we're not seeing any listings for SQL Server Services. Any ideas?</p>
