An exception of type 'System.Data.Entity.Core.EntityException' occurred in EntityFramework.SqlServer.dll but was not handled in user code

I am new to ASP.NET MVC, I am facing this exception, the connection string looks perfect but still, the exception is raised, appreciate if anyone give me why is happening.

Thank you guys

Model 1

namespace MVCTwice.Models
{
    public class StudentContext : DbContext
    {
        public DbSet<Student> studs { get; set; }
    }
}

Action method

           List<Student> emp=studentContext.studs.ToList();

<connectionStrings>
  <add name ="StudentContext " 
        connectionString ="server=.; database=here your database name; integrated security=SSPI"
           providerName ="system.data.SqlClient"/>
</connectionStrings>

Here is your code but change your database name and then add it into the web.config file.
