Interactive Window fails to execute when referencing functions across multiple files

Question

How can I successfully use the Interactive Window within F# when I reference functions across multiple files.

NOTE:

My solution builds. However, when I attempt to execute logic via the Interactive Window, I receive the following error:

The namespace or module 'Deck' is not defined

Answer 1

You can use #r to reference an assembly, or #load to load another F# script file (.fsx).

It's all described in the documentation.
