Question

I’m trying to test some F# code from the Beginning F# book but am getting ‘not defined’ error with the reference to ‘Seq.generate’. (I’m using VS2010 – so this may have worked with earlier vn of VS/F#)

FWIW I’ve also installed the F# Powerpack dll, but that does not seem to make a difference.

Is there a workaround/alternative here?

/// execute a command using the Seq.generate
let execCommand (connName: string) (cmdString: string) =
    Seq.generate
        // This function gets called to open a connection and create a reader
        (fun () -> openConnectionReader connName cmdString)
        // This function gets called to read a single item in
        // the enumerable for a reader/connection pair
        (fun reader -> readOneRow(reader))
        (fun reader -> reader.Dispose())

generate can be found in FSharp.PowerPack.Compatibility:Compat.Seq.fs
