What a wonderful idea! You could also use the same basic tech for DIY root canal, colonoscopies, ...
The possibilities are endless!

BinarySerializer is a very useful tool, with much less "ceremony" (annotations) required than DataContract. It does have its own brutal ways: it will serialize private Fields.
The fact my WinForm app created an instance of another project (generic 'ctor) separate from the Form, and then called its internally defined Serialize/Deserialize methods ... that in turn used BinarySerializer ...
Well I didn't expect it to break trying to serialize with an error saying the Form must be marked as Serializable: after all, a WinForm is a Control, and you can't serialize Controls.
I went back over every part of the code: external Class project has parameterless 'ctor: check.
There were some properties of Type Action in the external project that had code injected into them at run-time in the Form Load event: I recalled that BinarySerializer ignored Properties being said somewhen by Marc Gravell.
After much gnashing of teeth, I finally let go of fantasizing that some new Framework version had screwed things up, and, went in and added [NonSerializable] attributes on the Action Property definitions.
Whoops: that's illegal: with BinarySerializer, that Attribute works only on Fields. Changed Actions to Fields, and voila, things save and restore as expected.
And now, I'm going to go outside and cry, because I have proven to myself, again, that my tendency toward certainty is my relentless enemy, and I burn with shame.

I've never really liked the way the serializers work, but I understand why they work that way. I just wish there was a less ... kludgy way to do it.

There are some very interesting serializer projects on CP including Mehdi Gholam's epic (10 years of development !) FastJSON [^], and SuperLloyds Galador serializer [^] .
@superlloyd where's your CP article on Galador ?
cheers, Bill

You can add attributes to the backing field for auto properties / events by prefixing the attribute with field: - for example:
[field:NonSerialized]
public Action Foo { get; set; }
[field:NonSerialized]
public event EventHandler Bar; Attributes (C#) | Microsoft Docs[^]

Once again you have proved your eagle-eyes see all, know all 
Why the devil didn't I come across that in poring over the docs on BinarySerializer (again), and related threads on SO ?
The "field" prefix is mandatory on Properties of Type Action and Func ... and, I assume Predicate ... you don't want serialized, but, optional on Func and Action Fields you don't want serialized, where [NonSerialized] works fine.

... Version 91.0.4472.77 (Official Build) (64-bit)
Well, apparently it runs JS 25% faster than V90.x.y.z
And ... I have no way to measure it, but yes, it does seem faster to load CP pages on my Surface.
That may be me expecting to see improvement, but ... who knows?

Are you sure that is really due to it? Maybe the hamster got a redbull this morning

... that you can explain the purpose of in one (reasonable) line, say a sentence or two brief ones.
Mine is implementing a 2D polygon fill algorithm on a write only display device.
I know how in theory - vaguely - to do it, but it's mind bending to attempt in practice, and I say that as someone who writes old-school table based LR parsers.
UPDATE: Randor humbled me. There's an easy way to do this. I even knew about it at one point but blanked on it here. I am very grateful, despite feeling a little foolish.
My most complicated algo... probably GLR parsing. In terms of ones I haven't solved - there's one that should be simple but I can never get it right -> converting an NFA or DFA state machine into a regular expression.

Many (~ 500) moons ago, I had to write a line "fitting" program with some unusual constraints. None of the usual "least squares", "cubic spline" etc. methods did exactly what was wanted, so I had to roll my own.

Treating love like an algorithm might have something to do with it.

When "true love" is your patient, then, doctor, treatment "primum non nocere" is even more critical.
I find it fascinating that the original sigil of the Asclepian healing cult had only onw serpent twining around the staff, not two (as on the Caduceus of Mercury).

Given these truths:
o Time is money.
o Money is the root of all evil.
o Girls cost time and money.
We obtain
time = money
_____
money = V evil
girls = time x money
girls = money x money
_____ _____
girls = V evil x V evil
girls = evil
|
|
|
|
|
You forgot the branch cut - a square root has two solutions. This gives us:
time = money
_____
money = ± V evil
girls = time x money
girls = money x money
_____ _____
girls = ± V evil x ± V evil
girls = ± evil
This is closer to the real world, in that:
- Money may be either positive (credit) or negative (debit)
- Some girls are good
