I want a way to initialize hxbit at the right time in C#

[kyubuns]

I'm having trouble with the "Too late to register class" error.

#24
HaxeFoundation/haxe#4091
HaxeFoundation/haxe#7561

The answer is "Haxe's problem", but Haxe doesn't seem to have any plans to address it either.
Could you please provide a way for all classes to be initialized when you create the Serializer for hxbit, or manually initialize hxbit?

Right, I guess we could add some support for this in hxbit, or another way would be a way to "preload" (and thus force statics init) some classes in C#, I'm not sure how this would work since I'm not familiar with the platform.

Thanks for the reply!
In my opinion (I'm using C#), user calls hxbit.Serializer.init(), or initialize when the Serializer is created for the first time, it would be less likely to cause unintelligible errors than force calling static init of C# class.
(I don't know Java. Sorry.)

I'm going to post the code I want to work on for your reference.

class SerializeTest {
	static function main() {
		var serializer = new hxbit.Serializer();

		var a = new Hoge(5);
		trace('a = $a');

		var serializedA = serializer.serialize(a);
		trace('serializedA = ${serializedA.toHex()}');

		var b = serializer.unserialize(serializedA, Hoge);
		trace('b = $b');

		var serializedB = serializer.serialize(b);
		trace('serializedB = ${serializedB.toHex()}');
	}
}

class Hoge implements hxbit.Serializable {
	public function new(x: Int) {
		this.x = x;
	}
	@:s public var x: Int;
}

haxe -main SerializeTest -lib hxbit --interp
SerializeTest.hx:6: a = Hoge
SerializeTest.hx:9: serializedA = 0105
SerializeTest.hx:12: b = Hoge
SerializeTest.hx:15: serializedB = 0105

haxe -main SerializeTest -lib hxbit -cs serialize_test_cs && mono ./serialize_test_cs/bin/SerializeTest.exe
haxelib run hxcs hxcs_build.txt --haxe-version 4005 --feature-level 1

I have tried to fix this problem, but this fix is not very good.
This is because the initialization cost in non-C# languages has increased and the number of dependent libraries has increased.
If anyone else is having trouble and is waiting for an official fix, please refer to it.
