Adding new entity gives error: EntityCommandCompilationException was unhandled bu user code in Entity Framework

Question

I have 5 tables in started projects. If I adds new table (Urun entity) writing below codes:

project.BAL :

public static List<Urun> GetUrun()
{
   using (GenoTipSatisEntities genSatisUrunCtx = new GenoTipSatisEntities())
   {
      ObjectQuery<Urun> urun = genSatisUrunCtx.Urun;
      return urun.ToList();
   }
}

if I receive data form BAL in UI.aspx:

using project.BAL;


namespace GenoTip.Web.ContentPages.Satis
{
    public partial class SatisUrun : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                FillUrun();
            }
        }

        void FillUrun()
        {
            ddlUrun.DataSource = SatisServices.GetUrun();
            ddlUrun.DataValueField = "ID";
            ddlUrun.DataTextField = "Ad";
            ddlUrun.DataBind();
        }
    }
}

I added URun later. error appears ToList method: EntityCommandCompilationException was unhandled bu user code
