F# is a functional-first programming language that supports immutable data structures, tail call recursion, discriminated unions, partial application, and other functional programming features. The document recommends starting with simple F# katas and puzzles to learn the language, then writing simple programs like ant simulations to become more proficient. It also provides resources for learning from the F# community including user groups and reading recommendations to help get started with F#.

- 3. If you hate to code, you’ll love F#
- 4. Functional may be new to youbut F# is multi-paradigm. Start small, work your way up. Don’t be afraid to use what you know. Some problems will start to scream “This would be much easier in F#!”
- 5. Try some simple Katas and PuzzlesProject Euler is a great place to start.See http://is.gd/TheRoadToFunctionalAnd http://is.gd/TheTedNewardChallenge
- 6. Write some Simple Ant AICheck it out at: http://is.gd/FSharpSilverlightAnts

Editor's Notes
- Who has used F# before?Who has made a significant project in F#?
- F# has a ton of new constructs to explore and will open your mind to completely new ways of doing things. Things you never thought possible before.You don’t need to understand of this stuff to enjoy F#, but it has a lot to explore if you’re into that kind of thing. Even if you don’t use F# professionally, just learning how these things work will make you a better programmer in general.
- If you care about getting things done quickly, and programming is just a means to an end F# can get you there quickly and safely.
- Start with a few simple problems. The first step is to get comfortable with the syntax and constructs.Even if you never use F# at work, learning it will make you a better programmer.
- Don’t be afraid to start out with object oriented and imperative code to get started. Just know that F# will push back. It wants you to write functional code.Don’t worry if the problems are easy, think of it as a structured way to play with F# constructs
- I wrote an ant colony AI simulation in Silverlight with uploadable AI. Give it a go when you get some time.
- F# has a lot of great graphics frameworks. Youcan make beautiful graphics with very little code.FsChart (left), VSLab (middle top), Tomas’s F# Library forLearning Graphics (top right), Jon Harrop F# for Visualization (bottom right)Tomas’s Graphics Lib: https://github.com/tpetricek/Documents/tree/master/Talks%202011/Teaching%20F%23%20(Community%20for%20F%23)
