one to one relationship with fluent api

Question

Model:

public class User {
    public Guid UserId { get; set; }
    public string UserName { get; set; }
    public virtual Membership Membership { get; set; }
}

public class Membership {
    public Guid UserId { get; set; }
    public DateTime CreateDate { get; set; }
}

DbContext:

public class UsersContext : DbContext {
    public UsersContext() : base("ApplicationServices") { }
    public DbSet<User> Users { get; set; }
    public DbSet<Membership> Memberships { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder) {
        modelBuilder.Entity<User>().ToTable("aspnet_Users");
        modelBuilder.Entity<Membership>().ToTable("aspnet_Membership");

        //insert relation here to join the two tables
    }
}

This is my first day playing around with the fluent api and i was just wondering how i would be able to join these two tables. How would i define the relation?

Also, any tutorials on the fluent API that have helped you?

Answer 1

You could use next code example:

    modelBuilder.Entity<User>()
                .HasRequired(u=>u.Membership)
                .WithOptional()
                .HasForeignKey(u=>u.UserId)
