Question

I know this is stupid question. I can create an empty class like the following in c#.

class Customer{}

But How can I do this in F#? This is my try

type Customer() =

   let _ = ()

What is the correct way?

Answer 1

Try

type Customer() = class end

Normally, you can leave the class and end tokens implicit and the compiler infers their presence at the beginning and end of the class’s definition, but if the class is completely empty you’ll need to specify them. Likewise, you can use struct end and interface end to generate structs and interfaces.
