C# and Visual Basic
Productive, multi-purpose, type-safe, object-oriented, open source
C# and Visual Basic are programming languages designed for creating a variety of applications that run on the .NET Framework. These languages are powerful, type-safe, and object-oriented. They are built on the .NET Compiler Platform “Roslyn” which provides rich code analysis APIs and it’s all open source on GitHub.
F#
Simple, efficient, data-rich, functional-first programming
F# is an open source, cross-platform, functional-first programming language that enables developers to tackle computing problems with simple, maintainable and robust code. F# is on GitHub, and many tools and libraries are available from the F# community.
ASP.NET web apps
