Hello @윤 종호,
Welcome to Microsoft Q&A forum.
Currently, Visual Studio 2022 doesn’t support .NET 9 even .NET 8, but in the future, probably, it will.
It is a little early to confirm this, as .NET 9 will be released in next year, there’s no 100% sure answer. Is there any particular reason why you need to confirm this?
You may check the document: Visual Studio 2022 Support for .NET Development/.NET blogs and wait for the latest information for the confirmation.
Have a nice day.
Sincerely,
Tianyu
