Resolution of Dependency failed

Question

Hey everyone. I'm getting an error while using Gallio to debug a unit test with vb.net code. The error does not occur when the program I'm trying to test is debugged using SOAPUI to pass the input in, only during unit testing with gallio.
Set Up
System.TypeInitializationException:
The type initializer for 'CP.Adapter.Tests.ServiceIOCSetup' threw an exception. --->

This is the class that the unit test is calling in it's setup section. It starts with the
Shared Sub New()
constructor but throws the error when it tries
loader.Load(container).

    End Sub
Once it is done with all this, when not debugging and failing, it calls a translator class which is meant to run this constructor, but if you don't do all of the IOC stuff above, it will throw an error saying that the IOC container is null, hence why I need
it to complete calling the class above. If anyone has any answers, I'd appreciate it.
Private _enumParser As IReferenceTableEnumParser
        Friend Sub New()
            _enumParser = IocContainerHelper.Resolve(Of IReferenceTableEnumParser)()
        End Sub

Man, you are talking Unity here.

Exception is: InvalidOperationException - The current type, PA.DPW.eCIS.Root.Core.Interfaces.ILoggingService, is an interface and cannot be constructed. Are you missing a type mapping?
It has something to do with the IoC and not Gallio that is deling with dependecy injection and mapping with the IoC I believe.  You should post to the Unity forum
