I apologize for my grammar and sentence structures, lol.. but even with the following nothing can be found under Profile:

System.Web.HttpContext.Current.Profile.backEnd = null; (I get a redline under backEnd..)

backEnd can not be found under Profile and web.config has the following structure:

<configuration>
   <system.web>
      <compilation debug="true" targetFramework="4.0"/>
      <profile>
         <properties>
            ...
            <add name="backEnd" type="BackEnd" serializeAs="Binary"/>
            ...
         </properties>
      </profile>
   </system.web>
</configuration> 

Since I'm new to ASP.NET and C# I would like to know if the file and folder structures of your Website/Application(Solution)
makes a difference when it comes to the Profile? I have those custom classes under App_Code, however the web.config,
aspx aswell as code-behind files are placed directly under the Website/Application(Solution) folder.. Did that make sense, lol?

Best regards
Richard
