A non collectible assembly may not reference a collectible assembly

[MikeTraceur]

Hello,

I am still failing to configure fluent nhibernate in my project. switching from java with spring and hibernate, nhibernate was my first choise and without the need to define mapping xmls it is now fluent nhibernate. But I always get this error

ystem.TypeInitializationException: The type initializer for 'Altv_Roleplay.Database.Config.NHibernateHelper' threw an exception.
 ---> FluentNHibernate.Cfg.FluentConfigurationException: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

 ---> FluentNHibernate.Cfg.FluentConfigurationException: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

 ---> System.TypeInitializationException: The type initializer for 'NHibernate.Cfg.NamedXmlDocument' threw an exception.
 ---> System.NotSupportedException: A non-collectible assembly may not reference a collectible assembly.

My Configuration looks like:

namespace Altv_Roleplay.Database.Config
{
    static class NHibernateHelper
    {
        private const string CurrentSessionKey = "nhibernate.current_session";
        private static readonly ISessionFactory _sessionFactory;
        static NHibernateHelper()
        {
            _sessionFactory = FluentConfigure();
        }
        public static ISession GetCurrentSession()
        {
            return FluentConfigure().OpenSession();
        }
        public static void CloseSession()
        {
            _sessionFactory.Close();
        }
        public static void CloseSessionFactory()
        {
            _sessionFactory?.Close();
        }

        public static ISessionFactory FluentConfigure()
        {
            ISessionFactory sessionFactory = Fluently.Configure()
                .Database(
                    MySQLConfiguration.Standard.ConnectionString(c =>
                        c.Is("Server=IP;Port=3306;Database=DATABASE;Uid=USER;Pwd=PASSWORD")
                    )
                )
                .Cache(
                    c => c.UseQueryCache()
                        .UseSecondLevelCache()
                        .ProviderClass<NHibernate.Cache.HashtableCacheProvider>())
                .Mappings(m =>
                {
                    m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly());
                })
                .BuildSessionFactory();

            return FluentConfiguration().BuildSessionFactory();
        }
    }
}

My Mapping:

namespace Altv_Roleplay.Database.Mappings
{
    public partial class AccountCharactersMapping : ClassMap<Accounts_Characters>
    {
        public AccountCharactersMapping()
        {
            Id(x => x.charId).GeneratedBy.Native();
            Map(x => x.charname);
            ...
        }
    }
}

My Entity:

namespace Altv_Roleplay.models
{
    public class Accounts_Characters
    {
        public virtual int charId { get; set; }
        public virtual string charname { get; set; }
        ....
    }
}        

I get this error when I try to open the session at:

    internal static void LoadAllPlayerCharacters()
        {
            ISession session = NHibernateHelper.GetCurrentSession(); // Here is when the Error appears
            using (ITransaction tx = session.BeginTransaction())
            {
               ...
            }

I also tried to add a hibernate xml config:

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
  <session-factory name="NHibernate.Test">
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="dialect">NHibernate.Dialect.MySQL55InnoDBDialect</property>
    <property name="connection.driver_class">NHibernate.Driver.MySqlDataDriver</property>
    <property name="connection.connection_string">server=SERVER;database=DATABASE;uid=USER;pwd=PASSWORD</property>
    <property name="show_sql">true</property>
  </session-factory>
</hibernate-configuration> 

But still no success. I tried it with netcoreapp3.1, net5.0 but now I am forced to switch to net6.0 due to other dependencies

@MikeTraceur what project type is this? Is it Xamarin?

Try running sgen on NHibernate.dll and include NHibernate.XmlSerializers.dll to your project.
