The loop does not work in a separate WPF thread

Question

The program starts, but does not display the interface.

public MainWindow() { Browser.Manage().Window.Maximize(); InitializeComponent(); Main.Content = new Pages.MainPage(); this.Dispatcher.BeginInvoke(new Action(() => { while (true) { RuCaptchaBalance.Text = Rucaptcha.GetBalance(); } })); }

No, this cycle is performed in the main thread - Pavel Mayorov

I think you want this:

 public MainWindow() { Browser.Manage().Window.Maximize(); InitializeComponent(); Main.Content = new Pages.MainPage(); RunMainLoop(); } async void RunMainLoop() { while (true) { RuCaptchaBalance.Text = await Task.Run(() => Rucaptcha.GetBalance()); await Task.Delay(1000); // делаем вычисления не подряд, а через разумную паузу } }

Regarding the theory of why, read this question .
