oh wait reading up on dependency injection, I do think I've used this before (at the very least in other languages), at least if it's just about passing through dependencies as a parameter in a constructor, I feel like that just happens naturally in OOP

✅ Inconsistent accessibility: property type is less accessible than property.

main problem I'm immediately running into trying to do that is that I actually have 3 different lists (I only mentioned one because the number was irrelevant to my problem) they have different custom objects (though they all inherit from the same abstract base class) but I'm not entirely sure how I'd pass all 3 lists as a single parameter in C#

assuming a <ListView> in UWP counts, then yes

I read information from a CSV file (though not because I want to) it's basically like this:

FileOpenPicker fileOpenPicker = new FileOpenPicker();
fileOpenPicker.FileTypeFilter.Add(".csv");
StorageFile result = await fileOpenPicker.PickSingleFileAsync();
if (result == null) return;
string csvText = await FileIO.ReadTextAsync(result);
using (StringReader reader = new StringReader(csvText)) {
  string line;
  while ((line = reader.ReadLine()) != null) {
    string[] cells = line.Split(',');
    ...
    MyList.Add(new CustomObject(cells));
    ...
  }
}

FileOpenPicker fileOpenPicker = new FileOpenPicker();
fileOpenPicker.FileTypeFilter.Add(".csv");
StorageFile result = await fileOpenPicker.PickSingleFileAsync();
if (result == null) return;
string csvText = await FileIO.ReadTextAsync(result);
using (StringReader reader = new StringReader(csvText)) {
  string line;
  while ((line = reader.ReadLine()) != null) {
    string[] cells = line.Split(',');
    ...
    MyList.Add(new CustomObject(cells));
    ...
  }
}

right tbh it might not need to be static anymore because I changed the code up this issue was (hopefully) the last hurdle in that change xD

yup, turns out it was because my CustomObject class wasn't public :D thanks for the help guys!

How to set a default method for an optional parameter in a method.

Something like that was actually gonna be my next step, so thanks a lot! After rewriting my own code to look be more similar to yours, I have this:

T GetInput<T>(string prompt = "> ", Func<T, bool>? condition = null, string errMsg = "Please enter a valid value.") where T : IParsable<T> {
    while (true) {
        Console.Write(prompt);
        bool valid = T.TryParse(Console.ReadLine(), null, out var value) && (condition?.Invoke(value) ?? true);
        if (valid) return value;
        else Console.WriteLine(errMsg);
    }
}

T GetInput<T>(string prompt = "> ", Func<T, bool>? condition = null, string errMsg = "Please enter a valid value.") where T : IParsable<T> {
    while (true) {
        Console.Write(prompt);
        bool valid = T.TryParse(Console.ReadLine(), null, out var value) && (condition?.Invoke(value) ?? true);
        if (valid) return value;
        else Console.WriteLine(errMsg);
    }
}

My only concern now is that the value being returned might be null.
