Answer 1

Screenshot says that there is a problem between your application and sql server. Application cannot connect to the server. Possible reasons:

1. Connection string values/format.
2. No server or server down.
3. Network problems.

Answer 2

Your EF connection string is using the "old" (since VS 2015 if I'm not mistaken**) way of connecting to localdb. You can see your DefaultConnection using the "new" way.

So:

<add name="MovieDBContext" connectionString="Data Source=(LocalDB)\MSSQLLocalDB;...`

Not: Data Source=(LocalDB)\v11.0...

**Since SQL Server 2014 Express Local DB

Hth...
