I have been on the search for a .NET library which supports writing 7z archives, it seems that this library does not support it since I am getting Archive Type does not have a Writer: SevenZip errors.

Is this something that will be implemented in the future? I understand that 7z format is a lot more complex than other formats like ZIP and TAR.

Happy to help contribute as well 🙂.

If this was a PR, I would accept it. But no, it currently doesn't support writing 7z files. It's an awful format, imo.
