C# is described as 'Multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines' and is a very popular programming language in the development category. There are more than 50 alternatives to C# for a variety of platforms, including Linux, Windows, Mac, BSD and Web-based apps. The best C# alternative is Python, which is both free and Open Source. Other great apps like C# are Java, C++, Rust and C (programming language).
