Why does my brain respond to this by hearing an imaginary voice saying: 'loose caboose' ?

Quote:
caboose (n.)
1747, "ship's cookhouse," from Middle Dutch kambuis "ship's galley," from Low German kabhuse "wooden cabin on ship's deck;" probably a compound whose elements correspond to English cabin and house (n.). Railroading sense "car for the use of the conductor, brakeman, etc.," is by 1859.

WeakReference broken in .NET5

Back to home project after.. a long break!
(hence my recent numerous programming posts) OMG | :OMG:

Upgrading my utilities to .NET5, running the tests and then this test broke....

var wo = new WeakReference(new object());
GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced);
Assert.False(wo.IsAlive);

Wow really? Floored Unsure | :~

Work with .NET4.7.2, fails with .NET5
Out of curiosity tried .NET6 (preview). Work again in .NET6, phew.. Rose | [Rose]

EDIT
After some reflection, it's most likely GC.Collect() that is broken in .NET5.... little harm done...

Are you running this in a debug build? If so, try a release build instead.

Using LINQPad 6, I can reproduce the behaviour you're setting in a debug build for .NET 5.10; toggling the "o+" switch at the bottom-right to switch to release mode returns the behaviour to normal.

It indeed work in Release build.

For anyone wondering why... this is not because the release build is optimized - it is because extra IL is being injected into the debug build for debugging usability reasons.

If you have:

{
  var thing1 = new thing1();
  // Do things to thing1
  var thing2 = new thing2(thing1);
  // Do things to thing2
  // "Breakpoint here"
}

On the breakpoint, you would expect to be able to see thing1. But as the garbage collector no longer see any reference to thing1 it can be collected as soon as the constructor of thing2 is done with it (the constructor does not even have to return).

To avoid this the compiler will inject IL to keep the variable "used" until he variable is out of scope seen from C# (or whatever language) - so the closing }.

Not sure how much "optimization" is really done in release. Maybe it is really just a "stop bloating" option - at least when I had to look I found release IL is a lot easier to read than debug IL Smile | :)

There's so many bugs in .net5 that it's not funny anymore.
This is the last one we found that affects us, in something as basic as Directory.GetFiles: .Net Core Directory.GetFiles() operates webDav path · Issue #46723 · dotnet/runtime · GitHub[^]. Still untriaged after eight months.
"Move fast, break things" has its place. The basic runtime for a lot of business applications in the world is not that place.

It is my little informed opinion the F-35 Pilot Helmet can be built by private engineers at much lower cost than .4 Million smackaroonies I seek here opinion of same by those more knowledgeable and skilled than myself The abilities of the helmet as far as I know are image presentation and head tracking Perhaps this is a kind of CodeProject X-Prize - Cheerio

PS As near as I can tell it is Google Glass w/ a carbon fiber shell Big Deal As for ruggedization specification fitting development E/M protection etc. FOUR HUNDRED MILLION DOLLARS! NONSENSE

Built? Yes.

Designed, built, tested and maintained with expected lifetimes and enforcing clauses on said lifetimes? Nope. Keep in mind that it's not a Samsung / Crapple phone, which expected volume of sales is in the millions. These are objects sould in the hundreds, maybe.
