c++ - Why my UWP GUI doesn't update the output?

Question

I have written a routine what receives data (Imagedata) via TCP/IP. I want to display the Imagedata in "Realtime" in TextBlocks on my GUI while the datatransfer is ongoing.

Unfortunately the GUI doesn't display the Text in Realtime, although the datatransfer ins working and the content of color_VDS[] is changing. The content just displays the content if the connection is canceled.

I was thinking of writing the code asynchronous but I don't think that makes any sense.

Maybe it has something to to with the settings of the solution???

The code is written in C++/CX in Visual Studio.

Thanks for your input

That's my minimal reproducible example.

void App1::MainPage::ShowNum(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
    int i = 0;

    while (1)
    {
        Connection->Text = i.ToString();
        i++;
    }
}
