is there any way to make something be checked for every time a field is updated or do i need to use

In the same CurrentEnergy setter, you can then check if the new value equals the max energy, and if so, increment output by Phase3()

You should probably check the new value of CurrentEnergy before actually updating it. Setting a value in a property getter is typically a nono

Refactor this if statement without an additional method

This is one way I find myself doing a lot:

KryptonWorkspaceCell? cell = SpaceControl?.ActiveCell;
bool hasZeroPages = false;
if (cell == null || (hasZeroPages = cell.Pages.Count() == 0))
{
    if (hasZeroPages)
        SpaceControl!.Root.Children!.Remove(cell)

    cell = new KryptonWorkspaceCell();
    SpaceControl!.Root.Children!.Add(cell);
}

KryptonWorkspaceCell? cell = SpaceControl?.ActiveCell;
bool hasZeroPages = false;
if (cell == null || (hasZeroPages = cell.Pages.Count() == 0))
{
    if (hasZeroPages)
        SpaceControl!.Root.Children!.Remove(cell)

    cell = new KryptonWorkspaceCell();
    SpaceControl!.Root.Children!.Add(cell);
}

Find popup window in Wpf

You could use reflection to access the Window._showingAsDialog field, then iterate it using Application.Current.Windows.Cast<Window>().Where(x => x.Parent == targetParenttWindow && IsOpenedAsDialog(x))

Update an enum in a child class

The thing about OOP is sometimes you have to redefine the same properties for different classes because extending a base class isn't really possible, and if you ever run into that, you might have to use some sort of composition class that contains those properties that can be shared across different types. You might not run into it, but it's an annoying thing to deal with when using complicated inheritance 😛

Update an enum in a child class

Then the oil and gas tankers derive from that class, and then you could do what you're doing now where the oil and gas tankers have their own enum things

Update an enum in a child class

Or create a class between Containerschip and the oil/gas tanker classes that has those properties like lengths, voluime, etc.

Update an enum in a child class

Having your oil tanker class derived from the gas tanker class seems a bit odd though, would it not be better to make them both extend Containerschip?

Update an enum in a child class

I've never seen this type of enum usage where each derived class has its own publicly exposed set of enum properties. I would just use something like a string in this case

Update an enum in a child class

You could check the range in the constructors but that gets weird for the base class constructors

Yeah, or merge all the values of the different Lading enums

I would probably use a string to represent that value instead of an enum

Making a field eligible for GC

Maybe try create a new list with a million (boxed) long values, then sum them all and print to console (to ensure it won't get JIT'd out)

Making a field eligible for GC

If it's anything like java then Collect is just a hint, it might not actually collect and it might not collect everything (it might decide to collect things in gen0, but _entities might be in gen1 or gen2 because it's a field)

Is volatile necessary when using a lock to read/write the variable?

I can't remember what C's was but i think it's something like if you access a volatile variable 3 times and write 2 times, it will always do exactly that and won't read/write any caches

C#'s one is just it prevents reordering of read/write operations and stops the variable being cached right?
