Body
Your scenario is analogous to the linking of Store and Products in the example given in the <a href="http://wiki.fluentnhibernate.org/Getting_started" rel="nofollow noreferrer">Getting started with Fluent NHibernate</a>. UserRoles is just a linking mechanism so you are better off not thinking of it as an entity. Instead, you have a User that has been assigned Roles and/or a Role that has been assigned to Users. So you might have: <pre><code>public class User { public virtual int Id { get; private set; } public virtual string DisplayName { get; set; } public virtual string Email { get; set; } public virtual string Password { get; set; } public virtual IList<Role> Roles { get; set; } public User() { Roles = new List<Role>(); } public AddToRole(Role role) { role.Users.Add(this); Roles.Add(role); } } public class Role { public virtual int Id { get; private set; } public virtual string RoleName { get; set; } public virtual string RoleDescription { get; set; } public virtual IList<User> Users { get; set; } public Role() { Users = new List<User>(); } } public class UserMap : ClassMap<User> { public UserMap() { Id(x => x.Id); Map(x => x.DisplayName); Map(x => x.Email); Map(x => x.Password); HasManyToMany(x => x.Roles) .Table("UserRoles"); } } public class RoleMap : ClassMap<Role> { public RoleMap() { Id(x => x.Id); Map(x => x.RoleDescription); Map(x => x.RoleName); HasManyToMany(x => x.Users) .Inverse() .Table("UserRoles"); } } </code></pre>

1. COOh man, you are awesome! That did the trick. A few things I added from the example: Added constructors to User & Role entities to initialize the IList to a new List of the respective object. Add virtual AddUser, AddRole methods to the respective entities for adding users & roles. I was then able to successfully make calls to NHibernate to save the data. That is just so freaking awesome. Thanks again! I knew the answer was in the example, but I just couldn't piece together what I was missing. I remember it saying relationships like this must be mapped on both ends, but I didn't know how. Thx

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
