I want to store profile properties in XML file but i am facing Error "Could not load type 'System.Web.Profile.XmlProfileProvider'." and tell me the provider name for this

In Web.Config

<providers>
</clear>
<add name="XmlProfileProvider"; type="System.Web.Profile.XmlProfileProvider"
                     applicationName="/" fileName="Profiles.xml" folder"~/App_Data/"/>
<providers>
<properties>
   
   <add name="Code" allowanonymous="true">
   <add name="Name" allowanonymous="true">
</properties>

C# code

HttpContext.Current.Profile.SetPropertyValue("Code","0001");
