I believe you always need navigation property on at least one side when using code-first. Then you will be able to map it:
public class User
{
public string UserId { get; set; }
public string PasswordHash { get; set; }
public bool IsDisabled { get; set; }
public DateTime AccessExpiryDate { get; set; }
public bool MustChangePassword { get; set; }
public int RoleId { get; set; }
public Role Role { get; set; }
}
public class Role
{
public int RoleId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
}
public class Right
{
public Guid RightId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public int RoleId { get; set; }
public Role Role { get; set; }
}
public class TestContext : DbContext
{
public TestContext() : base("Entities")
{}
protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<User>()
.HasRequired(r => r.Role)
.WithMany()
.HasForeignKey(r => r.RoleId);
modelBuilder.Entity<Right>()
.HasRequired(r => r.Role)
.WithMany()
.HasForeignKey(r => r.RoleId);
}
}
