Refactoring Singleton Overuse

Question

Today I had an epiphany, and it was that I was doing everything wrong. Some history: I inherited a C# application, which was really just a collection of static methods, a co

Great question. A few quick thoughts from me...

static in C# should only be used for data that is exactly the same for all instances of a given class. Since you're currently stuck in Singleton hell you only have one instance of everything anyways, but once you break out of that this is the general rule (at least, it is for me). If you start threading your classes you may want to back off on static usage because then you have potential concurrency issues, but that's something that can be tackled later.

I'm not sure how your hardware actually works, but assuming that there's some basic functionality that's the same across all of them (like, how you interface with them at a raw data level or similar) then this is a perfect instance to create a class hierarchy. The base class implements the low level / similar stuff with virtual methods for descendant classes to override to actually properly interpret the data / feed it onward / whatever.

Good luck.
