Specify ON DELETE NO ACTION in ASP.NET MVC 4 C# Code First

Question

How do I specify ON DELETE NO ACTION Foreign Key Constraint in my model designs?

At present, I have:

public class Status
{
    [Required]
    public

You can either disable it for your entire context by removing the cascade delete convention in the OnModelCreating method:

  protected override void OnModelCreating( DbModelBuilder modelBuilder )
  {
     modelBuilder.Conventions.Remove();
  }

or, you can do it per relationship using a fluent mapping (also in the OnModelCreating):

EDIT: you would put it in your menu entities

public class MenuEntities : DbContext
{
    public DbSet Statuses { get; set; }
    public DbSet Restaurants { get; set; }
    public DbSet Menus { get; set; }

      protected override void OnModelCreating( DbModelBuilder modelBuilder )
      {

         modelBuilder.Conventions.Remove();

     modelBuilder.Entity()
        .HasRequired( f => f.Status )
        .WithRequiredDependent()
        .WillCascadeOnDelete( false );

     modelBuilder.Entity()
        .HasRequired( f => f.Status )
        .WithRequiredDependent()
        .WillCascadeOnDelete( false );

      }

}
