FluentFramework 1.2.4

Implementation

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. Also you can expand and improve your FluentNHibernate configurations on here.

public class DefaultConnection : IConnectionDescriptive
{
    public FluentConfiguration Configuration(FluentConfiguration cfg, bool useSecondLevelCache, bool useQueryCache, out bool useDefaultCachingMechanism, out bool autoCreateDatabase)
    {
        autoCreateDatabase = true;
        useDefaultCachingMechanism = true;
        return cfg.Database(SQLiteConfiguration.Standard.ConnectionString("Data Source=Database.db;Version=3;"));
    }
}

2. Create entities as like below;

public class Book : Entity<DefaultConnection>
{
    public virtual string Name { get; set; }
    public virtual User User { get; set; }
}

3. Map your entity as like below;

public class BookMap : EntityMap<Book, DefaultConnection>
{
    public BookMap()
    {
        Map(x => x.Name).Not.Nullable();
        References(x => x.User).Not.Nullable();
    }
}

4. Get your database connection as like below;

public User GetUser(string username)
{
    var repository = Repository<DefaultConnection>.CreateRepository();
    return repository.Query<User>().Where(x => x.Username == username).SingleOrDefault()
}

5. You can also use transactions easy like below;

public void AddBook(string bookName, User user)
{
    var repository = Repository<DefaultConnection>.CreateRepository();
    repository.Transaction.Begin();
    var book = new Book { Name = bookName, User = user };
    repository.Add(book);
    repository.SaveChanges();
    
    if(!doSomethingWithBook(book))
    {
        repository.Transaction.Rollback();
    }
}

Examine the project to see what you can do more.
