WPF project - cannot import the namespace

I’m
developing  WPF projects, not Winforms. I have added the
Lexactivator.vb file without any issues. I have copied the .dll file
into the Debug and Release folders. However, Lexactivator does not show
up in the Project References and thus my project cannot Import the
namespace.

Hi,

In order to access the API functions you will do following:

Cryptlex.LexActivator.SetProductFile()

You need to use the Cryptlex namespace
