Hi,

I am developing a web app,in asp.net 2.0 using C#.I am following DDD,by eric evans,so i am building my domain first.Now,for persistance i wana use NHibernate..will it require me to code my classes in a certain way like needing to have getter/setter for propeprties etc..or any class can be persisted..is there any best practice i can follow?
thks

Some compromises will have to be made and some rules obeyed - collections have to be used through interfaces (IList, not List<T> or ArrayList) for example, but your objects will not have to depend on NHibernate for any functionality.

What I really want to know,do I have to use DAO type pattern for my domain objects,and this DAO will be used by nhibernate?
Say,i have a class which is immutable,how will nhiberrnate save this object,as it will not have any getter/setter,object is constructed fully only through constructor..
thks

Your objects have to have a no-argument constructor which may be private. NHibernate can also access private fields (through reflection) to set their values.

The DAO question is sort of orthogonal - use DAO if you want to, don't use it if you don't want to - DAO is a layer above NHibernate, so NHibernate doesn't care.

thks sergey..how do i do the mapping for the private fields in the xml file?
using property tag?
Also,reading doc on persistent classes,says..
Declare accessors and mutators for persistent fields..is it mandatory?..just a bit confused..

Declare them using <property ... access="field" /> or access="nosetter.camelcase" or substitute camelcase by whatever other naming strategy you use for the fields.

It's not mandatory to have getters and setters (accessors/mutators) declared, it's just easier to explain and performs slightly better.

thks a bunch..
