  1. Create an implementation as like below and configure your connection. You can use different database connections instead of SQLite of course! Others are in FluentNHibernate.Cfg.Db namespace.
public class DefaultConnection : IConnectionConfigurer
    public IPersistenceConfigurer Configuration()
        return SQLiteConfiguration.Standard.ConnectionString("Data Source=Database.db;Version=3;");
  1. Adding configuration to service example.
public partial class App : Application
    public App()
        ConnectionDescriptors.Add<DefaultConnection>(true, false, false);
  1. Entity example;
public class Book : Entity<DefaultConnection>
    public virtual string Name { get; set; }
    public virtual User User { get; set; }

    public override bool OnPreInsert()
        return Name != "maybe a banned word check?"; //cancel

    public override bool OnPreUpdate()
        return true;

    public override bool OnPreDelete()
        return true;
  1. Mapping example;
public class BookMap : EntityMap<Book, DefaultConnection>
    public BookMap()
        Map(x => x.Name).Not.Nullable();
        References(x => x.User).Not.Nullable();
  1. Query example;
public User GetUser(string username)
    using (var repository = new Repository<DefaultConnection>())
        return repository.Query<User>().Where(x => x.Username == username).SingleOrDefault();
  1. Transaction example;
public void AddBook(string bookName, User user)
    using (var repository = new Repository<DefaultConnection>())
        var book = new Book { Name = bookName, User = user };
