I have to describe interconnection between objects. public class Entity { public string Name {get;set;} public IList<Entity> Connections {get;set;} } How can i persist this?

I have a class generated from a WSDL that has a bunch of public properties and a public event. I'm extending this class with my own and adding some properties to it. All of my own properties are declared virtual, but the base class properties are not virtual. I'm using Fluent NHibernate's ClassMap to map only the properties from my exte...
I'm importing data that may or may not exist already in my database. I'd like NHibernate to associate any entities with the existing db one if it exists (probably just setting the primary key/id), or create a new one if it doesn't. I'm using S#arp architecture for my framework (MVC 2, NHibernate, Fluent). I've added the [HasUniqueDoma...

And if so, what are the implications of setting it on one end vs. the other? Some more clarification: I'm setting both sides of the relationship: Parent.Children.Add(child); Child.Parents.Add(parent); In a cas...
Is there a way to setup SQLite connection pooling using Fluent NHibernate configuration? E.g. equivalent of DataSource=:memory: would be: var sessionFactory = Fluently .Configure() .Database(SQLiteConfiguration.Standard.InMemory) (etc.) Is there something eqivalent to "Pooling=True;Max Pool Size=1;"? ...
I have this class: public class MyEntity { public virtual int Id { get; set; } public virtual IList<Point> Vectors { get; set; } } How can I map the Vectors in Fluent NHibernate to a single column (as value)?

Do mapping attributes offer the same versatility as nhib hbm's do? Can you use them together with FNH to handle things FNH doesn't yet do as well as hbm's can? Cheers, Berryl By mapping attributes, I don't mean hbm files; there are apparently attributes that come with NHib (or maybe NHib contrib these days) that you use to decorate you...
Hi, I have a many-to-many mapping defined (only relevant fields included) with FluentNHibernate (v1.0.0.637): // MODEL: public class User : IPersistentObject { public User() { Permissions = new HashedSet<Permission>(); } public virtual int Id { get; protected set; } public virtual ISet<Permission> Permissions { ...

So, basically, I have two entities, which have two many-to-one relationships with each other. Their schematic is this: User: public class User { public virtual int Id { get; protected set; } ... publi...
