I might be missing a joke? but they are referring to NativeAOT, aptly named as it compiles a .NET application into a native binary ahead of time (instead of using a JIT.) The benefit being no dependency on the .NET runtime, faster startup time (but slower runtime performance, due to lack of JIT), lower memory footprint, and any other advantage you'd find in Go.
Yes, that's one of the points of NativeAOT, a self-contained single binary, exactly as Go does it.
No, you can create .exe files.
Yes, NativeAOT supports Windows, Linux and MacOS, x64 and Arm64.
Not sure about that, I suppose it depends on the targets each .NET version support. For example, .NET 8 will drop RHEL 7 and only RHEL 8 and later.
And to play devil's advocate: this won't work for all existing .NET applications. If you use reflection (which is AOT unfriendly), chances are that you will have to rework a ton of stuff in order to get to a point where NativeAOT works. There's a middle solution though, called ReadyToRun, which has some advantages compared to running fully with the JIT compiler.
I’m pretty sure that 70MB is including the entire .NET standard library, which is massive. Enabling NativeAOT or trimming reduces the size down to a few MB
My bad, the link I sent was not about NativeAOT, just bundling all the dependencies together (also, it's 4 years old). After a quick search, here's a recent SO question that mentions that you can build .exe files
As for the filesize... please recheck the post under which we are commenting. :D
I just don't get the obsession with small executable file sizes. 100 MB here and there hasn't mattered at all in desktop development for many years. Feels like arbitrary goals set up just to be able to say "look there are still uses for [unmanaged language]". And of course there are, but a 60 MB smaller executables on a desktop with several terabytes of storage just isn't one of them. And no, developer, about to comment about how you've only got 5 millibits of storage on your embedded system, we're not talking about that.
