.NET 8 Standalone 50% Smaller On Linux

This is a result of their focus on better serverless support. Having done that recently these are really welcome improvements along with AOT stuff for EF.

This is for native AOT binaries, not for the typical case. Though this release and the previous ones did contain improvements for trimming binaries, which is what you need to use to make non-AOT binaries smaller.

They also added a TimeProvider to help with testing time objects. Maybe one day we will also get an FileSystemProvider.. TimeProviderFake: https://learn.microsoft.com/en-us/dotnet/api/microsoft.exten... ReleaseNotes: https://learn.microsoft.com/en-us/dotnet/core/whats-new/dotn...

Until then you can use System.IO.Abstraction[1] if you aren't already :)

I wish people stopped using Medium for writing, it's a horrible reader experience.

Curious - why isn't it the typical case? .NET runtimes on Linux itself are rare enough, I figured AOT on Linux would be about the only use case, especially in containerized environments.

.NET uses a lot of reflection, and you need to replace that with other mechanisms for AOT.

And for modern .NET (previously named .NET Core, the version that also runs on Linux) you can package the runtime with the binary. You can even create single-file executables there, though those are still not AOT.

The main advantage of AOT is startup time, and that didn't use to matter much for the kind of applications .NET was used for. It matters more now with serverless stuff like AWS Lambda.

I second the request to not use medium. There are tons of better options. Neocities, bear blog, mataroa blog, and so on. There is no reason to suffer with medium and all the nagging.
