This will not compile as-is, but should get you started in the right direction:

private readonly BackgroundWorker worker
    = new BackgroundWorker { WorkerReportsProgress = true };

public MainWindow()
{
    InitializeComponent();

    worker.DoWork += worker_DoWork;
    worker.ProgressChanged += worker_ProgressChanged;
}

private void worker_DoWork(object sender, DoWorkEventArgs doWorkEventArgs)
{
    // Do some long process, break it up into a loop so you can periodically
    //  call worker.ReportProgress()

    worker.ReportProgress(i);  // Pass back some meaningful value
}

private void worker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    prgBar.Value = Math.Min(e.ProgressPercentage, 100);
}
