TFS code review how to review code against older version that is not prior version or version in a different branch

Question

We would like to use the TFS 2012 Code Review but ran into a snag where we need to compare the current version to the version from 3 changes ago (or compare it to the version in a different branch (e.g. Main or Release branch).

Does this type of compare along with adding comments/overall comments during the Code Review exist in TFS?

Is it possible to do that?

Answer 1

Today it is only possible to do a Code Review on a specific changeset (or shelveset). That means only one revision. If you wanted to do what you are suggesting, the only way to do it today would be to initiate 3 code reviews, one for each of the 3 changesets.

Something we (the TFS MVP's) have been asking Microsoft for a while, is the ability to do a code-review on many changesets at once (which is effectively what you're asking for).

There is a User-Voice suggestion which covers the multi-changeset review and other Code Review related features, go and vote on it: http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/2670048-make-code-review-feature-usable
