Using Thread.Sleep in Xamarin.Forms

Question

I want to execute the following

MainPage = new ContentPage
{
    Content = new StackLayout
    {
        Children =
        {
            new Button
                 


        

Answer 1

If you want to wait

asynchronously: await Task.Delay(10000);

synchronously: Task.Delay(10000).Wait();

But please try to avoid blocking the UI thread to ensure a good user experience and keep your app responsive.

Using Thread.Sleep in Xamarin.Forms

There are two Xamarin.Forms templates:

• Xamarin.Forms Portable Class Library

  Because of the PCL subset mechanism, you have no chance to get Thread.Sleep.

  Update 2017: PCLs are deprecated, now. If you use .netstandard 2.0, you can use Thread.Sleep as you are used to it.

• Xamarin.Forms Shared Project

  This Template contains different platforms that do not support Thread.Sleep. Windows UWP, Xamarin.Android and Xamarin.iOS support it, Windows Phone 8.1, and Windows 8.1 not. If you unload/delete the 2 projects, the solution builds. (don't forget using System.Threading; in your App.cs)

Answer 2

You can try to use

await Task.Delay(milliseconds);

if you want to put a delay in your thread.

For blocking you can do

Task.Delay(TimeSpan.FromSeconds(5)).Wait();
