A Guid value-type that converts to and from 26-char alphabetic strings - like ShortGuid, but better.

Good for URLs!

using MiniGuids;

var miniGuid = MiniGuid.NewGuid();

//implicit conversions (and vice-versa too)
string someString = miniGuid;
Guid someGuid = miniGuid;

//explicit stringifying and parsing
var str = miniGuid.ToString();
var sameMiniGuid = MiniGuid.Parse(str);

//works out-of-the-box with Json.NET, MVC, etc. via TypeConverters
var json = JsonConvert.SerializeObject(new { miniGuid }); //{ "miniGuid": "aaaaaBBBBBcccccDDDDDeeeeeF" }

It's all about readability: ShortGuid compresses to 22 chars by also including numbers and two special characters (_ and -) - this leads to complicated-looking identifiers like _-9g5YdI9A27c_a-2FC00ebQ2.

MiniGuid in comparison always outputs a blob of letters - all in the same character class, and without strange pepperings of underscores etc. It's a trade-off - four more characters, but more regular and digestable: QxLKubVCxzzuTSKvxxizlZfyyg.

Also (not insignificantly) MiniGuid is nicely hosted on GitHub, nicely packaged with implicit conversions etc, and (drumroll) compatible with .NET Standard.
