Things that may be confusing when moving to F#

I have been doing C# for quite a few years, and I have started using F# recently. I am only occasionally coding in F# so I tend to forget some things from one time to the other. So here's what I must remember:

• The sequence of F# code files in Visual Studio matters!
• To have access to a module or type from another module, that module must be declared before (higher up) the other module.
• To move a module up, use Alt + ArrowUp.
•  Indentation matters!
• If some code is part of some enclosing element, that code must be indented.

Here's a great article:
