Hello Roel,

the Initialize method is private in the Membership class

You have to implement the Initialize method in your MembershipProvider derived
class.

The NameValueCollection holds the configuration values from the <membership>
element in web.config, e.g. "RequiresQuestionAndAnwer=true" - you have to
parse the collection to set the internal state in your class and the properties.

as i said - take the time to read the whitepapers i gave you the link to
- without completely understanding the architecture, you won't have much
fun with your provider.
there you will also find the source code of the depracated Access provider
as a template.
