Entity Framework Database not Updating, No Errors - entity-framework

Question

I've used add-migration and then update-database - both run with no errors, but the changes I am requesting to happen did not happen. I check my table data in the Server Explorer and it will not add the new column along with the other new data. I've attached my code if you need more of the code please let me know.
I did create another migration and copied the same changes to be added to the new changes to see if the new one would push. Migrations/Update2.cs and Migrations/Update1.cs are the same exact code.
//Migrations/Update2.cs "The updated Migration"
namespace EnrollmentApplication.Migrations
{
using System;
using System.Data.Entity.Migrations;
public partial class Update2 : DbMigration
{
public override void Up()
{
AddColumn("dbo.Courses", "InstructorName", c => c.String());
AddColumn("dbo.Enrollments", "Notes", c => c.String());
AddColumn("dbo.Students", "Age", c => c.Int(nullable: false));
AlterColumn("dbo.Courses", "CourseTitle", c => c.String(nullable: false, maxLength: 150));
AlterColumn("dbo.Courses", "CourseCredits", c => c.String(nullable: false, maxLength: 4));
AlterColumn("dbo.Enrollments", "Grade", c => c.String(nullable: false));
AlterColumn("dbo.Enrollments", "AssignedCampus", c => c.String(nullable: false));
AlterColumn("dbo.Enrollments", "EnrollmentSemester", c => c.String(nullable: false));
AlterColumn("dbo.Students", "StudentFirstName", c => c.String(nullable: false, maxLength: 50));
AlterColumn("dbo.Students", "StudentLastName", c => c.String(nullable: false, maxLength: 50));
}
public override void Down()
{
AlterColumn("dbo.Students", "StudentLastName", c => c.String());
AlterColumn("dbo.Students", "StudentFirstName", c => c.String());
AlterColumn("dbo.Enrollments", "EnrollmentSemester", c => c.String());
AlterColumn("dbo.Enrollments", "AssignedCampus", c => c.String());
AlterColumn("dbo.Enrollments", "Grade", c => c.String());
AlterColumn("dbo.Courses", "CourseCredits", c => c.String());
AlterColumn("dbo.Courses", "CourseTitle", c => c.String());
DropColumn("dbo.Students", "Age");
DropColumn("dbo.Enrollments", "Notes");
DropColumn("dbo.Courses", "InstructorName");
}
}
}

}
There's zero error messages but my changes are not applied.

Answer 1

I had to Delete the Migrations folder, Delete the database in the Server Explorer, and in the Windows Explorer, delete my database in the App Data folder. Reloaded the application and built the new database and everything went through properly.
