If we’ve learned nothing from Java and Python, it’s that managing runtimes and environment can be a huge pain point.
EDIT: swipe keyboard put ringtone instead of runtime and I missed it. Corrected.
This confused the hell out of me until I realized it's supposed to be runtime.
It's never been clear to me why someone would want this.
Not true since .NET Core 3.
$ dotnet publish --self-contained --runtime osx.11.0-x64 -p:PublishSingleFile=true
In .NET Core 3, you can build and distribute a single-file executable which, when run, will actually unpack an executable and a ton of DLLs into a temp directory, and run it from there.
In .NET 5 they changed it, so that when you build a "single-file" executable, you actually get an executable plus a few DLLs, which must be distributed together.
Python OTOH...
