Question

If in F# I have methods like:

drawBox
drawSphere
paintImage

Would they be transferred to C#, exactly the same?

If that’s the case, then wouldn’t it compromise the naming conventions in C#, where methods are supposed to be PascalCase?

Or should I make them PascalCase in F# as well to remedy this?

Answer 1

You should follow the F# Component Design Guidelines.

The notable parts are:

• Do use the .NET naming and capitalization conventions for object-oriented code, including F#-facing libraries.
• Do use either PascalCase or camelCase for public functions and values in F# modules.
  camelCase is generally used for public functions which are designed to be used unqualified (e.g. invalidArg), and for the “standard collection functions” (e.g. List.map). In both these cases, the function names act much like keywords in the language.

Another way to slice it:

• members and types should always be PascalCase, just like C#
• let-bound entities in modules can be camelCase, but this stuff is typically not stuff you’d expose publicly out of a library that is intended to be consumed by C#
