I'm trying to determine if the user has been authenticated. I was using the following code before changing Providers:

' Check for a logged in user;
Dim aUser As MembershipUser = Membership.GetUser()

If aUser IsNot Nothing Then
Me.LoginStatus1.LogoutText = String.Format("Welcome, {0}! (click here to log out)", aUser.UserName)
End If

Since installing your MySQL providers, I now receive the following error message:

System.ArgumentNullException was unhandled by user code
Message="Value cannot be null.
Parameter name: username"
ParamName="username"
Source="CoreLab.MySql.Web"
StackTrace:
