Hi I was searching for a long time for a OR-framework with linq support.

At the Time i am trying to get my own sample started. The project consists off only two classes: My Entity and another Form. But each time i want to save my object i get stackoverflowerrors....

Is there a really small sample for Do4.0 ? Because everything i downloaded is for 3.9....

Or can anyone help me with my code ?

private void Connect()
        {
            var config = DomainConfiguration.Load("mssql");
            config.Types.Register(Assembly.GetAssembly(typeof(AdressModel)), typeof(AdressModel).Namespace);
            domain = Domain.Build(config);
            domain.OpenSession();
            AdressModel hurz = new AdressModel();
            hurz.Phone = "123";
            hurz.Session.Persist();
        }

and my mapping code

[HierarchyRoot(typeof(KeyGenerator),"ID")]
    public class AdressModel : Entity
    {
        [Field]
        public long ID { get; private set; }

        [Field]
        public string Phone { get; set; }

        public static object AllAdresses()
        {
            var bla1 = from adressmodell in Query<AdressModel>.All
                   select adressmodell;
            return bla1;
        }
    }

Hi!

i don't think that it is an problem with DO. I don't get started with the samples you provide. Is there any very small sample on which i see the use of domain, session and transaction ?

The following code does not insert an Adress either :-/

var config = DomainConfiguration.Load("mssql");
            config.Types.Register(Assembly.GetAssembly(typeof(AdressModel)), typeof(AdressModel).Namespace);
            domain = Domain.Build(config);

            using (domain.OpenSession())
            {
                AdressModel hurz = new AdressModel();
                hurz.Phone = "123";
            }

DA gets an Connection to the Server, because the Tables have been generated...

ok, thanks, now i'am a step closer to the goal of my sample - inserting a phone number.

With the code you provided, the application inserts exactly one row - no matter how often i execute it. the inserted row contains an id , an typeid, but my value (phone number ) is null :-(

One question to the transaction scope,in the sample you ship with, the transaction scope isn't used and works fine? Why?
