I'm using V4.0.4.2 on Net 2.0 with Umbraco Membership rather than Asp.net Membership becasue it's the only way I've been able to get YAF running inside Umbraco.

I want to register members programmatically to add some extra functionality but
I can't get this to work. Here's my code:

------------------------------------------------------

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using umbraco.cms.businesslogic.member;

namespace MyApp.usercontrols
{
    public partial class RegisterBeta : System.Web.UI.UserControl
    {
        public void Page_Load(object sender, EventArgs e)
        {

        }

        protected void RegisterMember()
        {

            string userName = txtUserName.Text, password = txtPassword.Text, email = txtEmail.Text;

            MemberType regMemberType = MemberType.GetByAlias("Registered");

            Member newMember = Member.MakeNew(
                userName,
                regMemberType,
                new umbraco.BusinessLogic.User(0));

            newMember.Email = email;
            newMember.Password = password;

            newMember.Save();

        }
    }
}

 ----------------------------------------------------------------------
 
 When I try to build or compile this (using VS 2008) I get the following error:

"The type or namespace name 'BusinessLogic' does not exist in the namespace 'MyApp.umbraco' (are you missing an assembly reference?)... "

I have umbraco.dll, cms.dll and business.dll all referenced and that seems okay because there is no error in the header statement "using umbraco.cms.businesslogic.member;" also I can see each of the subordinate namespaces in Intellisense as I type it. When I type 'umbraco' inside the partial class, however, all I get is 'schemas'

This has me at my wits end because I'm badly behind on a project and I just can't see what the problem is. I'd greatly appreciate anyone throwing any light on it.

Thanks
