如何在Visual Studio 2010的C＃（和XNA）类中使用F＃库

Question

I have developed a little game using XNA 4.0 and C# (new Project->Windows Game 4.0 ). Now I have to refactor all the game logic and write it in F#.

I created a new project for my F# library(new Project->F# Library), and added the XNA library to the project's references.

Now, how can I include the F# library inside my C# project?

Answer 1

I assume the problem is referencing your F# library project from your C# one, rather than using the XNA library from in your F# project.

In the same way you'd reference a C# project:

Add the F# project to your solution and add a reference to the F# project in your other one

Answer 2

Compile the F# library and include it into your solution. I had to do this a while back to get the Financial Functions library: http://blogs.msdn.com/b/lucabol/archive/2008/12/04/financial-functions-for-net-released.aspx

Answer 3

I don't have my own experience with writing XNA libraries in F#, but I suppose that you may need to change some project properties to be able to reference the F# library from C# XNA application. I don't know exactly which project settings need to be changed, but there are two online templates that you can download and use as a starting point:

• F# Windows Phone Library
• F# Library for Windows Phone (XNA)

Aside, you can also find them if you click on "Online Templates" in the "New Project" dialog in Visual Studio and search for "F# XNA". There is quite a few, very useful, templates contributed by the F# community!
