distributed caching help

i am perplexing put distributed caching play, i'm controlling .

it requires vigilant being cached serializable, here category object.

[serializable]
public category members 
{
    open members()
    {}

    open members(string aspnetusername, twine aspnetpassword,
        twine emailaddr,string location)
        : this(0,0,aspnetusername, aspnetpassword,emailaddr,datetime.now, location,
        0,0,datetime.now,datetime.now,datetime.now,false)
    { }

    open members(int64? row,int memberid, twine aspnetusername, twine aspnetpassword,
        twine emailaddr,datetime datecreated, twine location, int daimokugoal, int previewimageid,
        datetime lastdaimoku, datetime lastnotifed, datetime lastactivitydate, bool isactivated)
    {
        this.row = row;
        this.memberid = memberid;
        this.aspnetusername = aspnetusername;
        this.aspnetpassword = aspnetpassword;
        this.emailaddr = emailaddr;
        this.datecreated = datecreated;
        this.location = location;
        this.daimokugoal = daimokugoal;
        this.previewimageid = previewimageid;
        this.lastdaimoku = lastdaimoku;
        this.lastnotefied = lastnotifed;
        this.lastactivitydate = lastactivitydate;
        this.isactivated = this.isactivated;
        this.details = new lazylist<memberdetails>();
        this.blogs = new lazylist<memberblogs>();
        this.daimoku = new lazylist<memberdaimoku>();
        this.determinations = new lazylist<memberdeterminations>();
        this.encouragements = new lazylist<memberencouragements>();
        this.entries = new lazylist<memberentries>();
        this.friends = new lazylist<memberfriends>();
        this.stats = new lazylist<memberstats>();


    }



   open int64? quarrel { get; set; }     
   open int memberid { get; set; }
   open twine aspnetusername { get; set; }
   open twine aspnetpassword { get; set; }

   open datetime lastdaimoku { get; set; }
   open datetime lastnotefied { get; set; }

   open bool isactivated { get; set; }
   open lazylist<memberdetails> sum { get; set; }

   open lazylist<memberentries> entries { get; set; }
   open lazylist<memberfriends> friends { get; set; }
   open lazylist<memberstats> stats { get; set; }
}

the linqtosql populates class.

      }

but reason i am removing error

system.runtime.serialization.serializationexception: form 'system.data.linq.dataquery`1[[daimokubeta.mvc.data.memberdetails, daimokubeta.mvc.data, version=1.0.0.0, culture=neutral, publickeytoken=null]]' public 'system.data.linq, version=3.5.0.0, culture=neutral, publickeytoken=b77a5c561934e089' noted serializable.

memberdetails serializable too..so certain since thinks can't serialized
any ideas?
