Hereโ€™s a dive into what they are, how to use them in .NET, and best practices to make the most of UUIDs.

A ๐—จ๐—จ๐—œ๐—— is a ๐Ÿญ๐Ÿฎ๐Ÿด-๐—ฏ๐—ถ๐˜ ๐˜‚๐—ป๐—ถ๐—พ๐˜‚๐—ฒ ๐—ถ๐—ฑ๐—ฒ๐—ป๐˜๐—ถ๐—ณ๐—ถ๐—ฒ๐—ฟ that ensures uniqueness without requiring centralized management, making it ideal for distributed systems. UUIDs are valuable for applications where generating unique identifiers across different environments is essential.

Each UUID version serves specific purposes:

For additional versions, libraries like ๐——๐—ฎ๐—ต๐—ผ๐—บ๐—ฒ๐˜†.๐—จ๐˜‚๐—ถ๐—ฑ can help generate UUIDs such as Version 6, 7, or 8 for specific scenarios.
