FSX file extension - Microsoft Visual Studio F# script

What is fsx file? How to open fsx files?

File type specification:

Source code and script file type

fsx file icon:

The fsx file extension is associated with Microsoft Visual F# (F SHarp) development software.

F# is a programming language that provides support for functional programming in addition to traditional object-oriented and imperative (procedural) programming. The Visual F# product provides support for developing F# applications and extending other .NET Framework applications by using F# code. F# is a first-class member of the .NET Framework languages and retains a strong resemblance to the ML family of functional languages.

The fsx files are similar to the *.fs source code files created in this language with few extra capabilities.

The .fssscript files are meant to be run with the "F# Interactive" mode in Visual Studio. They are used for executing scripted F# code rather than compiling it into a .dll or .exe file.

Sometimes the FSSCRIPT file extension is used for the F# scripts instead.
