Billing.Api dependencies

[RubenDelange]

If I build the solution, I notice that the \bin folder of Billing.Api contains the following assemblies:

• Marketing.Events.dll
• Marketing.Internal.dll
• Sales.Internal.dll
• Shipping.Internal.dll

How did that happen?

OK, nevermind, shared ITOps dependency answers my question.
How could this be improved in a "real" scenario?
