Task<int> RunTaskCompletionSourceExample(int number)
{
    var taskCompletionSource = new TaskCompletionSource<int>();

    // Simulate some work
    Task.Run(() =>
    {
        if (number >= 0)
        {
            // When work completes successfully, set the result.
            taskCompletionSource.SetResult(number * 2);
        }
        else
        {
            // If there is an error, we can set the exception.
            taskCompletionSource.SetException(new Exception("Input should be a non-negative number"));
        }
    });

    return taskCompletionSource.Task;
}

try
{
    //Await the task
    int result = await RunTaskCompletionSourceExample(5);
    Console.WriteLine("Result is: " + result);
}
catch (Exception ex)
{
    Console.WriteLine("Error: " + ex.Message);
