I have a problem decoding HTML entities. I have tried using both 

System.Net.WebUtility.HtmlDecode()

and in hopes that it was simply because this was a lightweight version of HttpUtilities, I’ve tried 

HttpUtility.HtmlDecode()

as well.

My problem is that I need to decode from Entity names, not Entity Numbers.
(see this list http://www.w3schools.com/tags/ref_entities.asp )

Both of the beforementioned methods decode to and from entity numbers, NOT entity names.

    I dont really see your problem. If I test the decoding via WebUtility.HtmlDecode, all entity names that are listed in the link you posted are decoded:

    var encoded = ""'&<>¡¢£¤" +
              "¥¦§¨©ª«¬­®" +
              "¯°±²³´µ¶·" +
              "¸¹º»¼½¾¿" +
              "×÷ÀÁÂÃÄÅ" +
              "ÆÇÈÉÊËÌÍ" +
              "ÎÏÐÑÒÓÔÕ" +
              "ÖØÙÚÛÜÝÞ" +
              "ßàáâãäåæ" +
              "çèéêëìíî" +
              "ïðñòóôõö" +
              "øùúûüýþÿ";
var expected = "\"'&<>¡¢£¤¥¦§¨©ª«¬­®¯°±²³´µ¶·¸¹º»¼½¾¿×÷ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓ" +
                "ÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýþÿ";

Console.WriteLine(System.Net.WebUtility.HtmlDecode(encoded) == expected);

    This small snippet yields true.

    When it comes to encoding: The HtmlEncode function is implemented to work just this way. There is little you can do about that, except from implementing it yourself, which I would not recommend (dont reinvent the wheel if you dont really need to).
