C# Entity Framework Basics Extending Our Entity Data Model Using the Fluent API

Not really understanding how to construct a solution to this question...

I understand what the method call will do and have implemented it within my own code following along with the videos but don't understand how to use it here - I'm feeling like I'm missing some of the necessary info.

Context.cs
using System.Data.Entity;

namespace Treehouse.CodeChallenges
{
    public class Context : DbContext
    {
        public Context()
        {
            Database.SetInitializer(new DropCreateDatabaseAlways<Context>());
        }

        public DbSet<Course> Courses { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            ModelBuilder.Entity<CourseStudent>()
                .Property(cs => cs.Grade)
                .HasPrecision(4, 3);
        }
    }
}

The video has a good example of this.

At about 04:26 in the Overriding the Context's OnModelCreating Method video, there's a good example where the precision and scale were set on the ComicBook.AverageRating property. The class and property are different but the basic application will be the same.

I typed "ModelBuilder" instead of "modelBuilder", smh...

Right. Other than that, the changes you added to your code above look good. :+1:

Now about that name, either will work technically, but starting the name with a lower-case letter would follow the convention used throughout the course for parameter names.
