    HI all,

    I am having a bit of a problem. I am developing a ASP.NET based application based on telerik Open Access version 2010.2.714.1.

    Persistent classes are generated based on the existing SQL Server tables using Domain model design [Used to be reverse mapping]. I have used Repository pattern to access in DAL.

    DAL layer is in a different class project which is being referenced from ASP.NET web project. So that asp.net pages can make use of it.

    e.g.
    Sample Repostiory Class looks like

    namespace MyDataRepository.Admin
    {
        /// <summary>
        /// UserRepository class implements interface IUserRepository
        /// Reponsibile for All User relates functions
        /// Eg Authentication/Authorisation, User listing 
        /// </summary>
        public class UserRepository:IUserRepository
        {
            private MyDbContext  m_dataContext;
            public UserRepository()
            {
                m_dataContext = new MyDbContext();
            }
      public UserPortfolio GetUserPortfolio(User user)
            {
                UserPortfolio userPorfolio = (from userPort in user.UserPortfolios
                                                 where userPort.UserPortfolioDefault == true
                                                 select userPort).FirstOrDefault();

                return userPortfolio;
            }
       }
    }//end of namespace


    On the ASP.NET side,

    I am using something like,

    if (userObj.UserPortfolios.Count>0)
    {
    ...
    }

    Just to inform you that userObj is a persistent class and it is using lazy loading to get UserPortfolios from "UserPortfolio" table.

    user.UserPortfolios.Count returns NullReferenceException!! when I change my session State to SQL Server in web.config but the same code work when session state is "InProc".

    Please let me know what mistake have I made and what needs to be done so that it works in both sessionState modes.

    Many thanks.

    MG
