I am working on an API that is triggered using a custom Job scheduler. The API is in the form of .NET dll. Currently it contains 10-15 methods. Most of the methods are currently in testing phase. The client wants to push out a single method to the production. Yes, I mean if there are 10 methods in a DLL the client wants to push a single method like FetchOrders(order id) into the production.
How can I go about doing that?
