Alternatives to Conditional Compilation in C#

Question

What is the alternative to having code with conditional compilation in C#?

I have a class that has lots of code that is based on # ifdef .. After sometime my code is unr

Answer 1

Polymorphism.

Approach it the same way as you would any spaghetti code with lots of conditional branches on the same condition.

Abstract out the differences into a base class or interface.

Construct the concrete class depending on build (one #if). Pass the concrete object to your App, and then your app calls the methods defined on the interface.
