// Signature: static member StartAsTask : Async<'T> * ?TaskCreationOptions * ?CancellationToken -> Task<'T> // Usage: Async.StartAsTask (computation) Async.StartAsTask (computation, taskCreationOptions = taskCreationOptions, cancellationToken = cancellationToken)
A Task<TResult> object that represents the given computation.
The following code example demonstrates the use of Async.StartAsTask.
open System.Windows.Forms let bufferData = Array.zeroCreate<byte> 100000000 let async1 = async { use outputFile = System.IO.File.Create("longoutput.dat") do! outputFile.AsyncWrite(bufferData) } let form = new Form(Text = "Test Form") let button = new Button(Text = "Start") form.Controls.Add(button) button.Click.Add(fun args -> let task = Async.StartAsTask(async1) printfn "Do some other work..." task.Wait() printfn "done") Application.Run(form)
