It’s not. The Apple devs will tell you it’s a great time on Linux, just like the MS people will tell you the same for C#.
Rust wasn’t designed for any specific platform and you can tell. The ecosystem on Linux especially is fantastic.
I ship a lot of .NET on Linux these days, works great
Arguably the dotnet sdk now works better on Linux than Windows. For example, Windows Containers are "supported" only the marketing checkbox sense.
> Rust wasn’t designed for any specific platform
I suspect that Mozilla being the primary developer and sponsor for many years actually meant that compatibility with all major platforms was prioritised; Mozilla obviously care about stuff working on Windows, and run lots of builds on Windows + I imagine a number of Firefox developers (if not drive) at least own a Windows machine for testing Windows-specific stuff!
I call out Windows because I think generally software people go for Mac > Linux > Windows (although Mac > Linux may be slowly changing due to liquid glass).
