I found this function
Exec here http://fsharp.github.io/FAKE/apidocs/fake-processhelper-shell.html.
Target "UpdateTools" (fun _ -> Exec "cmd" )
But I keep getting this error, when I try to run it: "The value or constructor 'Exec' is not defined".
I'm new to FAKE and have not used F#, so forgive me if this should be obvious.
Can someone tell me why this api is not accessible like that?
