Hello Everybody.

I need to have an external application create users on my dotnetnuke site. In order to do so, I've decided to create a seperate DLL class.

In this DLL class I'm referencing the DotNetNuke.Security.Membership.AspnetMembershipProvider class, and I'm trying to use its public methods to manipulate memebers tables in the database.

However, It seems I am unable to initialize an object of the AspnetMembershipProvider class. When I try to run the following line of code:

DotNetNuke.Security.Membership.MembershipProvider memProvider = DotNetNuke.Security.Membership.MembershipProvider.Instance();

I get the following Exception

System.TypeInitializationException was unhandled
  Message="The type initializer for 'DotNetNuke.Security.Membership.MembershipProvider' threw an exception."
  Source="DotNetNuke"
  TypeName="DotNetNuke.Security.Membership.MembershipProvider"

       at System.Threading.ThreadHelper.ThreadStart()

Inner Exception:

{"Object reference not set to an instance of an object."}

Stack Trace:

Anyone has an idea what am I doing wrong? Is there a way to initialize a dotnetnuke membershipprovider outside a dotnetnuke site?

Thanks in advance for everyone who helps.
