title: Using Hangfire, connection string given in Startup.cs throws Cannot attach file as database error
body: <p>I'm utilizing Hangfire in my ASP .Net MVC Web App, it had installed successfully. I'd like to use the same LocalDb to store queued jobs for Hangfire to dequeue and process as I've used to stored data. However I'm running into the below error when I provided its connectionString or name defined in <code>Web.config</code> in <code>Startp.cs</code>. I've had no trouble adding, deleting updating data in the same localDb before hangfire.</p>
  
  <pre><code>Cannot attach the file 'c:\users\jerry_dev\documents\visual studio 2013\Projects\Hangfire.Highlighter\Hangfire.Highlighter\App_Data\aspnet-Hangfire.Highlighter-20150113085546.mdf' as database 'aspnet-Hangfire.Highlighter-20150113085546'.
  
  Startup.cs:
  
  public void Configuration(IAppBuilder app)
          {
              ConfigureAuth(app);
              app.UseHangfire(config =&gt;
              {
                  string hangfireConnectionString = @"Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-Hangfire.Highlighter-20150113085546.mdf;Initial Catalog=aspnet-Hangfire.Highlighter-20150113085546;Integrated Security=True";
                  config.UseSqlServerStorage(hangfireConnectionString);
                  config.UseServer();
              });
          }
  </code></pre>
  
  <p>My project Solution is named "Hangfire.Highlighter" </p>
