How to add assembly reference to use Quartz in Asp.net Website?

Question

I am working on a website in VS 12 and I need to schedule some task when the application starts for that I am using quartz 2.0.0 but I am getting the following error:

My website is hosted online.

Job scheduler class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Quartz;
using Quartz.Impl;


public class jobscheduler
{
    public static void Start()
    {
        IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();
        scheduler.Start();

        IJobDetail job = JobBuilder.Create<Class2>().Build();

        ITrigger trigger = TriggerBuilder.Create()
            .WithIdentity("trigger1", "group1")
            .StartNow()
            .WithSimpleSchedule(x => x.WithIntervalInSeconds(10).RepeatForever())
            .Build();

        scheduler.ScheduleJob(job, trigger);
    }
}

The job which I want to schedule:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Quartz;
using System.Data;
using System.Data.SqlClient;

public class Class2: IJob
{
    public void Execute(IJobExecutionContext context)
    {
        Class1 obj = new Class1();
        DataSet ds;
        ds = new DataSet();
        ds = obj.selecturls();    

        Random ran = new Random();
        int index = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add1 = ds.Tables[0].Rows[index]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add1"] = add1;
        int index2 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add2 = ds.Tables[0].Rows[index2]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add2"] = add2;
        int index3 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add3 = ds.Tables[0].Rows[index3]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add3"] = add3;
        int index4 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add4 = ds.Tables[0].Rows[index4]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add4"] = add4;
        int index5 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add5 = ds.Tables[0].Rows[index5]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add5"] = add5;
        int index6 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add6 = ds.Tables[0].Rows[index6]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add6"] = add6;
        int index7 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add7 = ds.Tables[0].Rows[index7]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add7"] = add7;
        int index8 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add8 = ds.Tables[0].Rows[index8]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add8"] = add8;
        int index9 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add9 = ds.Tables[0].Rows[index9]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add9"] = add9;
        int index10 = ran.Next(ds.Tables[0].Rows.Count - 1);
        string add10 = ds.Tables[0].Rows[index10]["urls"].ToString();
        System.Web.HttpContext.Current.Session["add10"] = add10;
    }
}

Global.asax file:

<%@ Application Language="C#" %>
<script runat="server">

    void Application_Start(object sender, EventArgs e) 
    {
        jobscheduler.Start();
        // Code that runs on application startup
    }

    void Application_End(object sender, EventArgs e) 
    {
        //  Code that runs on application shutdown
    }

    void Application_Error(object sender, EventArgs e) 
    { 
        // Code that runs when an unhandled error occurs
    }

    void Session_Start(object sender, EventArgs e) 
    {
        // Code that runs when a new session is started
    }

    void Session_End(object sender, EventArgs e) 
    {
        // Code that runs when a session ends. 
        // Note: The Session_End event is raised only when the sessionstate mode
        // is set to InProc in the Web.config file. If session mode is set to StateServer 
        // or SQLServer, the event is not raised.
    }
</script>

and I don't have any assemblyinfo.cs file because I selected an empty website instead of the new project.

If you downloaded Quartz 2.0.0 from the Internet you have to check dll's properties (right click on the dll in windows explorer -> Properties). It's possible that you have to unblock the library:

Another possible solutions you can find in that thread.
