Error: 'MachineToApplication' beyond application level'

I have a project which was converted from VS2003 to VS2008 throwing an  error while running the appln

"It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.
 This error can be caused by a virtual directory not being configured as an application in IIS."
<authentication mode="Forms">
      <forms loginUrl="Loginfrm.aspx" name="frmauth.aspxcookieauth2" protection="All">

You have multiple web.config files in your application.

Remove the second web.config file if not required.


If you are in IIS server, convert the folder which is having the second web.config file as Application.

Right-Click on the folder and Click Convert to Application.

Compiler Error Message: CS0234: The type or namespace name 'JScript' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
my question is How to Upgrade an ASP.NET Web Application from older version to new version ?
Lokesh B RDeveloperCommented:

In web.config file add this.

        <add namespace="Microsoft.JScript" />
