.NET constructor node reporting no public constructors

Hi all.

I am trying to make a .NET call to Microsoft.Win32.RegistryKey within mscorlib(2.0.0.0).  MSDN shows that there are several properities and methods available to use.  However when attempting to create a .NET constructor in LabVIEW, RegisrtyKey is displaying "This class contains no public constructors."

I would like to call the method for GetSubKeyNames.

If anyone has any ideas, I would appriciate some assistance.  Thank you in advance.
