Question

Consider the following code:

[<EntryPoint>]
let main (args: string []) = 

  let rec main time =
    let newTime = time + 2 // place a breakpoint at this line
    main newTime

  main 0

I am not able to place a breakpoint at the marked line. I meet such problems quite often when using recursive functions and it really makes me not to use them. Is there any simple solution for that?

EDIT: I create a brand new solution and my build command looks like:

‘—— Build started: Project: ConsoleApplication4, Configuration: Debug x86 ——

Answer 1

So it looks like, that it is a bug. I have already reported it to the F# team. So lets hope that they will fix it soon!
