A) What error do you get when there is a typo in the XML mapping file's
class-tab name-attribute value and you are using AddFile()?
In other words when the name-attribute value != the name of the class in
the class.cs file.
B) Without that typo, what error do you get when there is a typo in the
string passed into AddFile()?
C) What if the typo is in the value of the assembly-attribute or the
hibernate-mapping-tag and all else is without typos?
D) What if the typo is in the value of the namespace-attribute or the
hibernate-mapping-tag and all else is without typos?
E) How much of log4net helped you to deal with those errors?
I don't think this is what I had going on. Again I've gone through far to
many iterations of this for me to say that at times perhaps it wasn't.
But I did just find I can make a very easy demo of this.
Try it yourself.
VStudio 2015, new project / Web api / SPA.
Add in nHibernate 4.0 & log4net 1.2.15
Add config sections & configs to web.config.
-- here is my openSessoin
public static ISession OpenSession()
{
var cfg = new Configuration();
cfg.Configure(); // nHibernate config is setup in Web.Config
// AddFile() doesn't work. I don't care what they say.
Everyone is setting the propertry of the XML mapping file to "Embedded
Resource" for a reason.
cfg.AddFile(@"C:\Users\slyle\Desktop\Steves NHibernate
Playground\StevesnHibernatePlayground\MyFirstNHibernateSite\MyFirstNHibernateSite\Models\NHibernate\EmployeeList.hbm.xml");
//cfg.AddFile(@"C:\Users\slyle\Desktop\Steves NHibernate
Playground\MyFirstNHibernateSite\MyFirstNHibernateSite\Models\NHibernate\vEmployeeList.hbm.xml");
//cfg.AddFile(@"C:\Users\slyle\Desktop\Steves NHibernate
Playground\MyFirstNHibernateSite\MyFirstNHibernateSite\Models\NHibernate\spHireEveryone.hbm.xml");
ISessionFactory ses = cfg.BuildSessionFactory();
return ses.OpenSession();
}

I can make the error come and go as I please at run time by simply editing
EmployeeList.hbm.xml; EmployeeList.hbm.xml is not an embedded resource.
What errors do you get in all cases above?
How much does log4net help you in this case?
