Skype video 180 degree flip bug

Now this is the story all about how
MY VIDEO GETS FLIPPED, TURNED UPSIDE DOWN
And I'd like you to take a minute just sit right there
I'll tell you how it seems like I hang in mid air

On a three-screen setup, born and raised
On the middle screen is where I rest most of my gaze
Coding stuff, mailing, relaxing all cool
And all Skyping some colleagues, pairing .NET rules
When a touchscreen grabs my eye, now this looks good!
Order it on Amazon? Of course I should!
Flat on desk *under the main screen* but the cables go where?
I said "Display settings | Orientation | 'Landscape flipped'.  So there."

I called my mate on Skype and the video was here, the
Highest bitrate fresh and the audio was clear
If anything I could say all elements were there
But I thought "oh, FFS, I'm up in the air!"

I thought about trying Windows seven or eight
And I tried Zoom and WebEx - "Right way up! Skype you later!"
Clicked Skype | Help | Feedback - I was finally there
To log this bug down - hope you think that that's fair.

    A better c# string.Join supporting "and" or "or" for the final item

    C# developers often have to convert a list of items into a human-readable list.
    For example, if you have a string array: "a", "b", "c", "d", you may want the output to be:

    'a', 'b', 'c' and 'd'

    Here is a way to do that using a C# extension method:

    Comment welcome.  I will update with improvements as suggestions come in:

    Extension method:

      public static string ToHumanReadableString(this IEnumerable<object> enumerable, string quoteWith = "'", string delimitWith = ", ", string delimitLastWith = " or ")
      {
       if (enumerable == null)
       {
        return string.Empty;
       }
       var list = enumerable.ToList();
       return !list.Any()
        ? string.Empty
        : list.Count == 1
         ? $"{quoteWith}{list.Single()}{quoteWith}"
         : $"{string.Join(delimitWith ?? string.Empty, list.Take(list.Count - 1).Select(item => $"{quoteWith}{item}{quoteWith}"))}{delimitLastWith}{quoteWith}{list.Last()}{quoteWith}";
      }

      {
       Assert.Equal("'a'", new List<string> {"a"}.ToHumanReadableString());
       Assert.Equal("''", new string[] { null }.ToHumanReadableString());
       Assert.Equal("'a'", new[] { "a" }.ToHumanReadableString());
       Assert.Equal("'a' or 'b'", new[] { "a", "b" }.ToHumanReadableString());
       Assert.Equal("'a' or ''", new[] { "a", null }.ToHumanReadableString());
       Assert.Equal("'a', 'b' or 'c'", new[] {"a", "b", "c"}.ToHumanReadableString());
       Assert.Equal("'a', 'b', 'c' or 'd'", new[] {"a", "b", "c", "d"}.ToHumanReadableString());
       Assert.Equal("'a';'b';'c' or 'd'", new[] {"a", "b", "c", "d"}.ToHumanReadableString(delimitWith: ";"));
       Assert.Equal("'a', 'b', 'c' and 'd'", new[] {"a", "b", "c", "d"}.ToHumanReadableString(delimitLastWith: " and "));
       Assert.Equal("a, b, c or d", new[] {"a", "b", "c", "d"}.ToHumanReadableString(string.Empty));
       Assert.Equal("abcd", new[] {"a", "b", "c", "d"}.ToHumanReadableString(null, null, null));
       Assert.Equal("", ((string[]) null).ToHumanReadableString(null, null, null));
      }
