FluentNHibernate.Cfg.FluentConfigurationException.GetObjectData how to solve?


I have a website that uses FluentNhibernate and now I have uploaded this site to the provider but when I try to open the site it shows me some FluentNhibernate Exceptions. This site, on my computer, works very well without any problem, but the provider does not work. I looked for a few ways to try and fix this, and found some people with the problem msm and who were able to resolve Here , but I still could not get it to work.

How do I solve this problem?

    private static ISessionFactory session;

    private const String HOST = "domain.com";    //ip servidor

    private const String PASSWORD = "pass";         //senha banco
    private const String DB = "mydb";    //banco de dados

    //private const String HOST = "";    //ip servidor

    //private const String PASSWORD = "";         //senha banco
    //private const String DB = "mydb";    //banco de dados

    //cria conexao com banco de dados
    private static ISessionFactory createConnection() {

            //verifica se a sessao esta vazia se nao estiver retorna a sessao
            if (session != null)
                return session;

Sorry not to respond, but why do not you use mapping-by-code? It is native to NH, does not need another lib, and does not have these fluent zicas:
