Immediate Window constructor "Type 'class name' is not defined." issue

Question

I am having issues testing classes/functions with Visual Studio 2013 Immediate Window.

If I test my constructor in the Immediate Window-

test = new Config()

I get..

"Type 'Config' is not defined."

if I test a public function inside the Config class in the Immediate Window-

?GetConfigFromDatabase()

I get..

'GetConfigFromDatabase' is not declared. It may be inaccessible due to its protection level.'

The pseudo code for what I am testing is..

Friend Class Config
'Constructors and Destructors
Public Sub New()
    GetConfigFromDatabase()
End Sub


'Public Methods 
Public Function GetConfigFromDatabase() As Boolean
    '----Function stuff here
End Function

End Class 

I am not sure what simple thing I am doing wrong. I have tried a clean solution with rebuild, closing and reopening VS, but always the same thing. Thank you in advance!
