@o-l-a-v Thank you for your submission. Please note the build warnings about the links. See our contributor guide for information about links: https://learn.microsoft.com/powershell/scripting/community/contributing/general-markdown#hyperlinks

I removed the section you added about .NET 9 and UUID v7 support. I added a link at the top to the .NET 9 docs. PowerShell doesn't directly use the UUID v7 methods. Yes, you can call the method from PowerShell, but that is true for any .NET method.
