The type initializer for "NHibernate.Cfg.Configuration" threw an exception

Question

I am using FluentNHibernate and at the configuration stage I get the following error:

Here is the configuration:

public static ISessionFactory CreateSessionFactory () {return Fluently.Configure (). Database (MsSqlConfiguration.MsSql2000.ConnectionString (c => c.FromConnectionStringWithKey ("HighOnCodingConnectionString"))). Mappings (m =>
m.FluentMappings.AddFromAssemblyOf ()) .BuildSessionFactory (); }

And here is the error:

[failure] when_instantiating_a_session_factory.should_be_able_to_create_a_session_factory TestCase 'when_instantiating_a_session_factory.should_be_able_to_create_a_session_factory' Failed: type initializer for "NHibernate.CfgC made.

Here is the log information from FusionLog:

Answer 1

It looks like you have assembled against one version of the assembly, but at run time it finds another and complains. I suggest you turn on Fusion logging to find out what happens - in particular, the exact build that causes the problems!

Answer 2

I know that this was resolved long ago, but today, when I had this problem, I found it with my personal solution and thought that I was sharing knowledge:

https://forum.hibernate.org/viewtopic.php?p=2399679

From the post:

"My debugger in Visual Studio was set to break in all exceptions, setting the exception options fixed my problem."

Also led me to:

"After some searching, I found that the assembly xxxx.XmlSerializers is the pre-generated assembly that xmlserializers looks for before trying to generate it at runtime ..."
