ASP.NET Extensions to make it easy to create and use COMB (timestamped sequential) GUID variants for Microsoft SQL Server and PostgreSQL. See the GitHub site for more details.
A fast and modern .NET library to generate UUID/GUID that are either sequential and database friendly (versions 7), name based (versions 5) or random (version 4).
A Simple Unique Identifier (SUID) is (almost) unique like a GUID but only 7 characters !
There are five types of fixed size SUID :
* LettersOnlySuid : 14 lowercase letters
* UrlFriendlySuid : 10 url friendly characters
* FilenameSuid : 10 characters than can be used to create a filename
* Suid : 9...
