VersionedRestApi provides a simple but powerful attribute called 'ApiRoute' that
lets you annotate your Web API actions with versions (or version ranges).
Versioning is handled via the URI (as opposed to query string parameter, header, or body parameter).
See GitHub project readme for more details: https://github.com/RIDGIDSoftwareSolutions/versioned-rest-api
Fixed issue where routes stopped working at version 10 due to faulty regex.
