Entity Framework Code First - Fluent API Composite Primary Key
Example
By using the .HasKey() method, a set of properties can be explicitly configured as the composite primary key of the entity.
using System.Data.Entity;
// ..
public class PersonContext : DbContext
{
// ..
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
// ..
modelBuilder.Entity<Person>().HasKey(p => new { p.FirstName, p.LastName });
}
}
