Is there a command to update the interface immediately?

Question

I want to update the progress bar from 1 to 100 with this code.

for (int i = 0; i <= 100; i++) {
    System.Threading.Thread.Sleep(100);
    progressBar1.Value = i;
}

But as a result, the UI freezes until the loop ends.

I know it Dispatchercan help, but I don't want to split the function.

Is there any command to update the interface immediately, for example.

for (int i = 0; i <= 100; i++) {
    System.Threading.Thread.Sleep(100);
    progressBar1.Value = i;
    UpdateUINow();
}

Edit: I am using WPF and I am using Thread.Sleep to simulate a lengthy process.

In fact, I want any team to like it Application.DoEvents. But I can not find this command in WPF.
