Types are here to help but with this power comes great responsibility. The deeper you allow an input to be used in your library/method the more it makes sense to put a well defined type contract on it. Exhaustive type definitions may show that the author doesn't have a understanding of a required interface, abstractions or pattern to use. I use c# professionally for 20 years and I love the type system. It helps to tell the contract about the types and functions you expect yet you can overcomplicate things if you really about to. c# makes it "hard" to create method type definitions and you should use interfaces to achieve the contract definition. This helps to avoid the inline type definition as it's done in typescript. My approach is to use types in typescript as I'm used to in c#.
