Error   186 'NEvoWeb.Modules.NB_Store.NB_Store_ProductDocInfo' does not contain a definition for 'Purchase' and no extension method 'Purchase' accepting a first argument of type 'NEvoWeb.Modules.NB_Store.NB_Store_ProductDocInfo' could be found (are you missing a using directive or an assembly reference?)   D:\archivi\www.cccc.it\www\DesktopModules\NBright\NBrightBuy\Components\NBrightBuyV2Utils.cs    99  71  NBrightBuy
