hi, thanks for the reference link, I am a bit worries to use Godot C# after knowing some issues reported since 2017 about using external editor like Visual Studio Code cannot generates signal connect routine, such as HERE.
It is a known issues not only happened to VSCode but other editors as well, understand Godot teams are working on primary functions at first but bug like this had been stranded around and delayed for FIVE years with no fix, I hardly can believe.
Sometime, may trigger misleading sensitive response from the Godot discord channels when posting such question about why this problem has no solution until today and often being asked to fix the bug ourselves the polite and rude ways.
I wondered why those Godot C# experts who replied, not looking into this problem after five years ?
