The official Godot engine supports C# as a scripting language, and Action Game Maker is based on Godot but currently only supports GDScript, will C# support be considered in the future?
No working C# web export in Godot 4.X. That’s a massive negative. Yes, I’m aware of the prototype Mono build. It’s not where near production ready.
I would not expect it before Godot splits C# support into a GDExtension. C# requires a whole other editor build and release templates. It’s not quite double the support load, but is outside the scope of an Editor fork that’s trying to offer Visual Scripting for no/limited coding designers
If you’re not interested in working with GDScript, you could try one of the other Godot bound languages. The GDExtension compatability should be resolved. Look for 4.3.x supporting releases.
