zerosharp VS Entitas

Not sure why you would want to use C# without it’s open source framework but here it is: https://github.com/MichalStrehovsky/zerosharp

C# without .NET is like C without glibc. Possible but you'll need another core library. For C# that would be something like Mono or ZeroSharp.

NativeAOT definetely can do bare metal, here's an example of a very basic EFI boot application:

Here's one example repo that uses that feature if you are interested: https://github.com/MichalStrehovsky/zerosharp

This is false. You can even make UEFI application in C#

check https://github.com/MichalStrehovsky/zerosharp/tree/master/efi-no-runtime

Kind of. There's https://github.com/MichalStrehovsky/zerosharp demonstrating some bare metal capabilities.

Github documentation for entitias looks like it is still good https://github.com/sschmid/Entitas-CSharp/wiki

For examples I usually turn to GitHub. It has numerous C# game engines. However, I find it easier to figure out implementations myself and use other engines only for API inspiration. There are also several C# ECS such as Entitas and DefaultECS that you can use if you do not want to create you own.
