What is a .FS file?
The .FS file extension is used for a FlexiSIGN Document, but it's also known for being a source code file for the F# programming language, which is made by Microsoft. F# is a special kind of programming language that is a bit like another language called ML. You can create these .FS files by using a part of Microsoft Visual Studio called Visual F#. These files are important because they contain the instructions or code that tell a computer what to do. Once you've written your code in an .FS file, you can use Visual Studio to turn that code into a program, which might be a .DLL (a kind of file that helps other programs run) or an .EXE (a file that is a program you can run on its own).
To open and work with an .FS file, you would typically use Microsoft Visual Studio 2022 or a newer version of the software. This is because F# is designed to work well with Microsoft's .NET library, which is a big collection of pre-made code that developers can use to make their programs do different things, like display graphics or connect to the internet. F# was first introduced to the public with the 2010 version of Visual Studio, showing that it's a relatively new language but has been around for a bit of time to establish itself.
