We are migrating from SharePoint 2007 to 2010. We used to use Forms Authentication for our portal and have a custom login.aspx page for authentication. In this login.aspx page code, it detects new user and will automatically create a user in the membership
However, in SharePoint 2010, System.Web.Security.Membership always points to the defaultProvider="i" which is the default membership provider that claims authentication provider forces.
So we are facing a big problem about how to create a user in the membership provider in the new login.aspx page. How can we handle this situation?
