I just started nHibernate , I tried quick start but I Receive this error when I try to run it :

“File or assembly name NHibernate.Examples, or one of its dependencies, was not found.”

All I did was this:
Making User class.
Making database .
Making User.hbm.xml as a map and define its Build action as Embedded Resources .
Add nhibernate.dll as a reference
And adding
using NHibernate;
using NHibernate.Cfg;
to top and Entering this code in my Page Lode :

Code:

Configuration cfg = new Configuration();
cfg.AddAssembly("NHibernate.Examples");

ISessionFactory factory = cfg.BuildSessionFactory();
ISession session = factory.OpenSession();
ITransaction transaction = session.BeginTransaction();

NHibernate.Examples.QuickStart.User newUser = new NHibernate.Examples.QuickStart.User();
newUser.Id = "joe_cool";
newUser.UserName = "Joseph Cool";
newUser.Password = "abc123";
newUser.EmailAddress = "[email protected]";
newUser.LastLogon = DateTime.Now;

// Tell NHibernate that this object should be saved
session.Save(newUser);

// commit all of the changes to the DB and close the ISession
transaction.Commit();
session.Close();

I know Its very firstly problem, but I really cant solve it by myself.
so please help me ;)

Are you sure that "NHibernate.Examples" is the name of your assembly ?

Try this:

Code:

cfg.AddAssembly( typeof(NHibernate.Examples.QuickStart.User).Assembly );

Make sure that "NHibernate.Examples" is in your /bin/ directory
(like g:/inetpub/wwwroot/nHibtest/bin/NHibernate.Examples.dll)

there is no NHibernate.Examples.dll
NHibernate.Examples is actually in User.hbm.xml, so I assume it must be in my own progtam dll
I do only Quick start
http://wiki.nhibernate.org/display/NH/Quick+Start+Guide

did I miss a dll ?

If the name of the assembly containing your entities is not NHibernate.Examples then, you must update:

<class name="NHibernate.Examples.QuickStart.User, TheNameOfYourAssembly" table="users">

in your mapping files (*.hbm.xml)
