Well, I’m currently writing a service and frontend, both in C# (Blazor for the UI), and using docker-compose to build and deploy them to a Raspberry Pi running Linux. So not only cross-platform, but cross-architecture as well.
This is not a new thing either. Since .NET Core was released almost 10 years ago, it has supported cross platform development.
