title: Relationship Between ASPNET Membership Provider Tables and Custom Membership Tables
body: <p>I went through a custom profile provider example a while ago and I am 
  now revisiting it. </p>
  
  <p>My database has all the dbo.aspnet_* tables created when I ran the aspnet registration
  wizard. In these tables I have aspnet_Profile which has a FK constraint pointing to aspnet_Users.</p>
  
  <p>I also have two tables in MyDB: The first, dbo.ProfileData, has a foreign key constraint
  pointing to dbo.Profile. </p>
  
  <p>What I want to understand is how the tables in MyDB relate to 
  those in dbo.aspnet_*. Shouldn't there be a foreign key constraint (or some kind of 
  relationship) between the profile tables in MyDB and the aspnet tables? Some discussion
  of how my custom tables relate to those provided by aspnet would be wonderful. </p>
  
  <p>Thanks in advance. </p>
