Using while loop in a command freezes window

Question

I have a button that executes a command, and it contains a while loop, the application freezes after I start the command, I have also tried to run it recursively but I got the same behavior, and using a timer is not an option, the task can't be called using an interval

In the future, post the relevant code when asking a question — Jonesopolis, Jul 30 '22 at 02:52
You can use Background worker and show progress bar on UI. Ref https://stackoverflow.com/questions/6481304/how-to-use-a-backgroundworker — SHAILESH BARIA, Jul 30 '22 at 03:11

You have to run the blocking section of your code in a separate thread. Running it on the main UI thread will freeze the UI.

You can use Tasks to do this.

using System.Threading.Tasks;

Task.Run(() => {
    while (condition)
    {
        // operation
    }
});

A background thread is not always the best or correct solution. It really depends on the actual code that is blocking. For example, using an async API would provide better performance. – BionicCode Jul 30 '22 at 16:19
