ASP.NET Versioning, Folders or Solutions

As the title reads I was wondering if when I introduce versioning to my REST API, if i should use version folders (like a v1, v2, v3 folder in my Controllers root folder) or if i should make seperate solutions in 1 project for versioning and how much sense that makes, considering this will be a very large scale project
