Error trying to delete current Member

Question

I have a .NET usercontrol running on an Umbraco website, and I'd like to be able to delete the current member from the codebehind (I realise that doesn't sound like a great plan, but this did work on a normal ASP.NET Forms site), but calling System.Web.Security.Membership.DeleteUser(usernameToDelete, trueOrFalse); gives me (on the page I'm redirecting to):

No member with username '[email protected]' exists
Exception Details: System.Configuration.Provider.ProviderException: No member with username '[email protected]' exists
[ProviderException: No member with username '[email protected]' exists]
   umbraco.providers.members.UmbracoProfileProvider.SetPropertyValues(SettingsContext context, SettingsPropertyValueCollection collection) +346
   System.Configuration.SettingsBase.SaveCore() +402
   System.Configuration.SettingsBase.Save() +109
   System.Web.Profile.ProfileBase.SaveWithAssert() +31
   System.Web.Profile.ProfileBase.Save() +72
   System.Web.Profile.ProfileModule.OnLeave(Object source, EventArgs eventArgs) +9025062
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +148
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

Why is it trying to set a property value after I've deleted the user and changed page? I can't see how to set / remove the current Umbraco member.

EDIT: I'm using umbraco v 4.11.1 (Assembly version: 1.0.4715.27659)

Here's the longest version of my logout code that I've tried that still gives the error:

// sort out problems with umbraco caches:
Member.RemoveMemberFromCache(Member.CurrentMemberId());
Member.ClearMemberFromClient(Member.CurrentMemberId());

Roles.RemoveUserFromRole(Page.User.Identity.Name, JobShopRoles.RoleNames.Candidate.ToString());

//logout from: http://stackoverflow.com/questions/412300/formsauthentication-signout-does-not-log-the-user-out
FormsAuthentication.SignOut();
Page.Session.Clear();  // This may not be needed -- but can't hurt
Page.Session.Abandon();

// Clear authentication cookie
HttpCookie rFormsCookie = new HttpCookie(FormsAuthentication.FormsCookieName, "");
rFormsCookie.Expires = DateTime.Now.AddYears(-1);
Page.Response.Cookies.Add(rFormsCookie);

// Clear session cookie 
HttpCookie rSessionCookie = new HttpCookie("ASP.NET_SessionId", "");
rSessionCookie.Expires = DateTime.Now.AddYears(-1);
Page.Response.Cookies.Add(rSessionCookie);
// Invalidate the Cache on the Client Side

Page.Response.Cache.SetCacheability(HttpCacheability.NoCache);
Page.Response.Cache.SetNoStore();
//END logout

System.Web.Security.Membership.DeleteUser(currentUser.UserName, true);

//TODO: this will consistently give an error trying to update a property on a deleted member. Qs:

What happens if you logout the current user from codebehind before deleting it?

It looks like the deleted user is still logged in and exists in the current session and therefore Umbraco profileprovider tries to do something with it...

EDIT: try these 2 methods after the FormsAuthentication Logout and see if it helps:

Member.RemoveMemberFromCache(Member.CurrentMemberId());
Member.ClearMemberFromClient(Member.CurrentMemberId());

Edit2:

I looked into the UmbracoProfileProvider class to see what is causing the error:

   public override void SetPropertyValues(SettingsContext context,
 SettingsPropertyValueCollection collection) {

                string username = (string)context["UserName"];
                bool authenticated = (bool)context["IsAuthenticated"];

                if (String.IsNullOrEmpty(username) || collection.Count == 0)
                    return;

                Member m = Member.GetMemberFromLoginName(username);
                if (m == null)
                    throw new ProviderException(String.Format("No member with username '{0}' exists", username));


                foreach (SettingsPropertyValue spv in collection) {
                    if (!authenticated && !(bool)spv.Property.Attributes["AllowAnonymous"])
                        continue;

                    if (m.getProperty(spv.Name) != null)
                        m.getProperty(spv.Name).Value = spv.PropertyValue;
                }

            }

You can see your exception message after the provider is trying to retrieve the current Member, based on the username. Either way your context still contains a UserName or the SettingsPropertyValueCollection count is > 0 so it seems your code to logout the member is still leaving something behind.

Try this part instead of all the logout code you have:

   Member.RemoveMemberFromCache(Member.CurrentMemberId());
   Member.ClearMemberFromClient(Member.CurrentMemberId());
   FormsAuthentication.SignOut();
   Roles.DeleteCookie();
   HttpContext.Current.Session.Clear();
   System.Web.Security.Membership.DeleteUser(usernameToDelete, false);

this removes and clears the member from cache and client, signs out, deletes the Role cookie and clears the current session. Finally, after logging out, delete the Member by using its username.
