First of all, thank you for porting EnTT to C# #3
Description
I never imagined anyone would ever think of doing this so I didn't bother searching before... but it looks like I was wrong.
The thing I'm most interested in is performance. Obviously it would be better than most ECS systems in C# that don't take GC or cache into consideration. However, I was wondering how close to native performance one can get to C++ when one would write an entire program out of EnTT with no object references.
I somewhat religiously depend on ECS for everything in C++ such that I almost never use native pointers for nearly anything. To my understanding, the only reason C# can be potentially slower than C++ is its GC and cache-unfriendly logistics. If we can bypass that with EnTT, would the performance technically be similar to native code?
I just needed to make sure, and know what really is going under the hood that can potentially be different from its C++ counterpart. But if what you promised is correct, this just about solves nearly all problems for me.
p.s. I would very much like at least a very simple prototype of documentation. On how to properly or partially serialize a component, for example, or marking it for automatic registration using attributes (does it work the same as Unity? SerializeField and such). And other stuff available in the original entt.
