How to make a delay in a UWP with C#

I'm new on this of C#, I don't know so much of it.
I'm trying to make an app that changes a TextBlock every second. The app is UWP and I'm using C#.
This is my code:

public sealed partial class MainPage : Page
    {
        public MainPage()
        {
            this.InitializeComponent();
        }

        public bool stop = false;

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            string input = TextInput.Text + " ";
            TextOutput.Text = input;
            string output = TextOutput.Text;

            for (int i = 0; i <50; i++)
            {
                output = output.Substring(1, output.Length - 1) + output[0];
                TextOutput.Text = output;
                Task.Delay(150);
            }
        }
    }

For now I've tryed Task.Delay(), Thread.Sleep() and others, but this doesn't stop the for-loop.
In fact, I've made the same app but for console, and the Thread.Sleep() works perfectly.
Can you help me, please?

You were pretty close, it's just that Task.Delay is a task, perhaps obviously. And you have to await (or continue) tasks:

    private async void Button_Click(object sender, RoutedEventArgs e)
    {
        string input = TextInput.Text + " ";
        TextOutput.Text = input;
        string output = TextOutput.Text;

        for (int i = 0; i <50; i++)
        {
            output = output.Substring(1, output.Length - 1) + output[0];
            TextOutput.Text = output;
            await Task.Delay(150);
        }
    }

the value you are passing into Task.Delay / Thread.Sleep is going be milliseconds not seconds.

I would try Thread.sleep(1000) // this will you a delay of 1 second.
