Entity Code first - required decimal

Question

I'm using the modelBuilder class. Setting a not null field is easy using IsRequired when the property is of type string. As soon as the type is of type decimal, intellisense is not showing the IsRequired method.

  public class CategotyConfig: EntityConfiguration<Category>
  {
        public CategotyConfig()
        {
            this.Property(x => x.Name).IsRequired();
        }
  }

How can I set a field of type decimal to be not null ? Without using attributes.

Answer 1

decimal (as opposed to decimal?) is already required, because it's non-nullable.
