I think a standalone "Hello World", built with .NET Core, is around 60-70 MB large on both Linux and Windows. The startup times are alright - slower on Windows than on Linux in my experience because of the file system performance.

Lower than this. If I use the AOT compile option with .NET Core 3.1 I get a 40MB binary which goes down to 10MB with the trim option.

Just like Go which embed it’s runtime, .NET Core binary compiled with AOT embed the CLR but, unlike Go, it has options to trim out the pieces that aren’t necessary, which I really like.

I did not know about PublishTrimmed and will try it out. Thank you.

I think this is one of those features that was a bit preview in 5 and you should use the just-released v6 for PublishTrimmed. There are also situations where it doesn't work out of the box (e.g. Winui3!)

Lol what?

What goes into a 70 MB implementation of 'hello world'?

It’s not a 70 MB implementation of Hello world. It’s a 70 MB compressed runtime with a standard library (or at least the most basic parts of it) and a couple KB "Hello world".

Why is the runtime so huge and why is so much of the standard library included?

Java ‘hello world’ compiled into a static binary is just a couple of MB.

If you use legacy .NET (which is preinstalled on Windows) a GUI Hello World is about 10 kB.
