Combining F# async functions

Question

I\'m a bit frustrated here. I know I\'ve got all the bits, but I can\'t work out how to combine them...

let saveImageToDisk path content =
    async {
               


        

Answer 1

You can combine the two using the async expression:

let getImages imageUrls =
    imageUrls
        |> Seq.map (fun url -> async {
              let! content = getImage url
              return! saveImageToDisk (topath url) content })
        |> Async.Parallel
        |> Async.RunSynchronously
