Get another writeline on second itteration

It's also pretty basic so I suspect a lot of the suggestions here are possibly out of reach without explaining more programming concepts

IDisposable ownership semantics

What you're saying about the GC is also not quite accurate either since .NET implements a generational garbage collector, it's not simply mark & sweep

IDisposable ownership semantics

This is irrelevant to the question. IDisposable is not supposed to be left to the GC to deal with.

IDisposable ownership semantics

this could be simplified by immediately constructing a new Bitmap from the one that has the Stream so that the originals can then be Dispose'd but that'll absolutely massacre performance.

IDisposable ownership semantics

the compounding issue is that if a Bitmap is constructed from a Stream impl, you can't Dispose() the stream until after the Bitmap is disposed

IDisposable ownership semantics

for reference, I'm cleaning up a bunch of code that currently leaks Bitmap all over the place

IDisposable ownership semantics

I know it's correct, I was hoping that in 2024 we don't still have to do this C-like crap. But I appreciate the validation 🙂

IDisposable ownership semantics

a lot of code I've seen that uses IDisposable types seems to essentially ignore the problem and hopes that the type has a finalizer that'll do the job when the GC gets around to collecting it

IDisposable ownership semantics

What I'm trying to express is code that complies with CA2000 - which requires that all IDisposable types aren't leaked.

IDisposable ownership semantics

This is primarily a question regarding whether or not C# has introduced any sort of syntactic sugar or support for a "nicer" way of expressing transfer of ownership.

IDisposable ownership semantics

the method has no obligation nor desire to catch exceptions. This is doing what finally would do, except we've now made it more long-winded because we'd have to rethrow, for no reason

IDisposable ownership semantics

we are returning a type that implements IDisposable, if the method causes Dispose() to be invoked on the object, it's now returning an unusable instance.

IDisposable ownership semantics

using is invalid because it would result in calling Dispose on the object it's returning.

Selecting and filtering from a list with full nullable safety & warnings as errors

meaning, if I understand this correctly, that ValueTuple/Tuple have no such constraints

Selecting and filtering from a list with full nullable safety & warnings as errors

I see, if I'm understanding this right, whether it's allowed to work or not is dependent on whether or not you define constraints: https://learn.microsoft.com/en-us/dotnet/csharp/nullable-references#generics

Selecting and filtering from a list with full nullable safety & warnings as errors

Arrays and structs that contain reference types are known pitfalls in nullable references and the static analysis that determines null safety. In both situations, a non-nullable reference might be initialized to null, without generating warnings.

:cough:

Selecting and filtering from a list with full nullable safety & warnings as errors

that makes structs a bit of a turnoff for me if they essentially have inferior nullability safety

Selecting and filtering from a list with full nullable safety & warnings as errors

I suspect this isn't unique to ValueTuple - I imagine this is applicable to all struct types and it seems this is by design: https://learn.microsoft.com/en-us/dotnet/csharp/nullable-references#structs
