Here is the code that I used to throw the exception back to the main thread to be caught.

class Program
{
    static void Main(string[] args)
    {
        CancellationTokenSource cancelToken = new CancellationTokenSource();
        Exception taskException = null;

        var timerTask = Task.Factory.StartNew(() =>
        {
            for (;;)
            {
                if (cancelToken.IsCancellationRequested)
                    break;

                ContinuousTask();

                Thread.Sleep(400);

            }
        }, cancelToken.Token).ContinueWith((t, o) => {
            taskException = t.Exception;
            ((Thread)o).Interrupt();
        }, Thread.CurrentThread, TaskContinuationOptions.OnlyOnFaulted);

        try
        {
            
            //do a bunch of tasks here

            //want to skip the do while and go to the catch if exception is thrown
            do
            {
                System.Threading.Thread.Sleep(200);
            } while (true);

        }
        catch
        {
            if (taskException != null)
                Console.WriteLine(taskException.Message);
        }
        
    }

    private static int _loopCounter = 0;
    public static void ContinuousTask()
    {
        int counter = 0;

        do
        {

            if (_loopCounter >= 3)
                throw new Exception("error");

            if (counter >= 5)
                break;

            counter += 1;
            System.Threading.Thread.Sleep(100);

        } while (true);

        _loopCounter += 1;
    }

}
