C# on Linux, as of the past 2 or 3 years, has been consistently improving with great tooling, good interop, is open source(MIT) and has the ability to package "native" versions of your app that contain the runtime at negligible space costs for distribution or deployment.

Give .NET 5 on Linux a try, you'll be surprised!

For me, the work this team has been doing is the example of the positive "change" Microsoft has brought to the open source space. A stellar language with great infrastructure.
