Connectionstring not resolving

Hi, I am trying out this download/sample to see the dashboard in ASP MVC, can you please tell me what is expected of the conn string below.
1. I ran the install script for SQL; however, when I re-configured/modify the conn string inside the web.config the debug version... its not picking it up... what do I need to do to get it working. Is this where I configure it? and am I doing it right?
2. Is the data seeded somewhere?
3. I see the views are in core project, and you only have a layout, I am guessing _layout will find and load those views on the local server, is this correct?

Please let me know, this is from the samples in ASP MVC and how can I see the dashboard to view the hangfire events/transactions

```
