So… I am a C# coder at heart, but F# is starting to fascinate me. Today I thought I would try and figure out the basics of getting the two languages to talk to each other.
From what I could tell on Stack Overflow, at least for now there will not be any Windows Forms / WPF exposed to F# (it is possible, but I am lazy and like VS to do as much as possible). Which leaves me thinking, where will I use F#.
I can immediately see a use for it in the Business Layer of my applications – which would mean that I would somehow have to figure out how to get F# and C# to play nice.
First Scenario – How do I pass data between F# and C#.
So I did the following. Made one solution with two projects in it (1 C# Console – which is my startup project, and added a F# library project to the solution).
I then added the F# library project as a reference to my C# project – All pretty standard stuff.
I then wrote the following code in a F# file…

type User =
Now I go to my C# Console Project and add the following code…
static void Main(string args)
var test = new User("Mark", 10);
And it works! C# sees my F# type and I can create it etc. So this is the very basics… but at least it is a starting point! If you are looking for a good reference which goes a lot more in depth then check out this post by Matthew Cochran.
