Using Profiles in ASP.NET

Im new to using Profiles in vb.net and trying to figure out what im doing wrong. In webconfig开发者_如何学JAVA I have the following code:

And in my vb code i'm trying to add to the profile by using this code:

 profile.FirstName = "John"

But I keep getting an error saying:

FirstName is not a member of profile.

Is there something im doing wrong?. I am trying to learn this through reading this book but it seems like there missing a step. Any help would be very much appreciated.

Make sure you define a ProfileProvider in your Web.Config such as SqlProfileProvider or the Table Profile Provider

Here an example, replace the YOURConnectionString and YOURApplicationName with string you use.

<profile defaultProvider="CustomProfileProvider" enabled="true">
        <providers>
           <add name="CustomProfileProvider"
                type="System.Web.Profile.SqlProfileProvider"
                connectionStringName="YOURConnectionString"
                applicationName="YOURApplicationName"
                description="Something" />
        </providers>
        <properties>
           <add name="FirstName" type="System.String"/>
        </properties>
</profile>
