The FetchVersions method is a static method of the Sandbox.Package class. It asynchronously retrieves a list of revisions for a specified package identified by the identString. This method is useful for obtaining different versions of a package, which can be helpful for version control or rollback purposes.
To use the FetchVersions method, you need to provide the unique identifier string of the package you are interested in, as well as a CancellationToken to handle task cancellation if needed. The method returns a task that, when awaited, provides a list of revisions for the specified package.

foreach (var revision in revisions)

Console.WriteLine($"Revision: {revision}");
