[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("Id,Name,EnteredBy")] FavoriteBand favoriteBand)
{
  if (ModelState.IsValid)
  {
    favoriteBand.EnteredOn = DateTime.Now;
    _context.Add(favoriteBand);
    await _context.SaveChangesAsync();		// hmm, what’s this
    return RedirectToAction(nameof(Index));
  }
  return View(favoriteBand);
}

I think await will pause until the async operation is done. HMM, I found a note (EF Core does not support multiple parallel operations being run on the same context instance. You should always wait for an operation to complete before beginning the next operation. This is typically done by using the await keyword on each asynchronous operation. At https://docs.microsoft.com/en-us/ef/core/saving/async) So I wonder why you would do an async save, and then disable it with an await statement.
