I am trying to get the aspnet membership UserId field from an anonymous 
user.
I have enabled anonymous identification in web.config :
<anonymousIdentification enabled="true" />
I have also created a profile:
<profile>
  <providers>
    <clear />
    <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 
         connectionStringName="ApplicationServices" 
         applicationName="/" />
  </providers>
  <properties>
    <add name="Email" type="System.String" allowAnonymous="true"/>
    <add name="SomethingElse" type="System.Int32" allowAnonymous="true"/>
  </properties>
</profile>
I see data in my aspnetdb\aspnet_Users table for anonymous users that have had profile information set.
Userid                                  PropertyNames   PropertyValuesString

I just need to find how to get the 'Userid' value.
It is not possible to use :
 Membership.Provider.GetUser(Request.AnonymousID, false);
The Request.AnonymousID is a different GUID and not equal to 36139818-4245-45dd-99cb-2a721d43f9c5.
Is there any way to get this Userid. I want to associate it with incomplete activity for an anonymous 
user. Using the primary key of aspnet_Users is preferable to having to create my own GUID (which I could do and store in the profile).
This is basically a dupe of this question but the question was never actually answered.
