It seems odd that this doesn't work. The code below is pretty simple, however I get the following error on the line with "args[1]":
"This value is not a function and cannot be applied. Did you forget a ';' or 'in'

The example code in my Expert F# book gets a value from an array using an index like below. Yet seems to never work for me. Can anyone help me out?

#light

let main() =
    let args = System.Environment.GetCommandLineArgs()
    let test = args[1]
    ()

do main()

Thanks!
