Create a new user through Silverlight and assign a role

Hi,

I am developing a module based silverlight project with an admin module and a user module.

I am using ASP.NET forms authentication, roles, and profiles application services as WCF services provided by System.Web.ApplicationServices namespace.

I want to give access to admin to be able to CREATE new users and assign roles through his module, instead of using the ASP.NET Configuration tool.

I looked in the System.Web.ApplicationServices namespace but could not find any methods to create a new user and assign roles.

All the methods provided in this namespace are only for accessing the credentials and verifying them, but not for creation of new users.

I will really appreciate if anyone could help me get this working.

Thanks,

Moin
