What would be the correct way of creating users in CMS5? Somthing similar to the "extranet user registration" in EPiServer 4.
Basicly, i need a form that allows users to register. Do i need to invoke the sqlMembershipProvider.CreateUser or is there a way to do this in EPi?
Check out the System.Web.Security.Membership.CreateUser method. It will in turn call the SqlMembershipProvider.CreateUser method if SqlMembershipProvider is your primary membership provider, but the way the architecture is built you should go through the Membership class.
There is also a built in CreateUserWizard control in ASP.NET that you can use, which will work with the Membership-class, if you just need something quickly.
