You can write a pre-condition which is run when you deliver a baseline.
What we've been discussing is how you would have such a pre-condition
validate something about all change-sets that are effectively being
delivered by delivering that baseline.

Logically, any rules that you have in place for validating delivery of
change sets should be applied to the delivery of baselines, since
logically a baseline is just a way of collecting a set of change sets,
and delivering them as a group. It would be prohibitively expensive
(and unnecessary) to run the check on every change set in the baseline,
since only the "new change-sets" in that baseline need to be checked
(i.e. change sets that aren't already in the stream you are delivering
to). But computing the list of new change-sets and applying change-set
rules to all of them can still be expensive, which is one of the issues
discussed in work item 53173 (and probably why that feature hasn't yet
been implemented).

So you could try to do that computation yourself, but that will be hard
for you to make acceptably efficient. So I believe that what is really
needed here is for the system to apply change-set deliver rules to
change sets delivered via baselines (i.e. work item 53173).

Does that mean I can't write any precondition which checks while
delivering a baseline ? Basically 2nd half of my initial query is
still not answered. i.e. I want to write the precondition for
delivering the baselines, so that all the change sets in the
baselines have workitem attached to them. My doubt is if one delivers
more than one baseline for same component in a single deliver
operation, how to find all the change sets under all those baselines
which are being delivered in single deliver operation ? Since API
only provides the method to get a single baseline per component.

Note that one workaround is to disallow the delivery of baselines, and
only allow the delivery of change sets.

You could use IFileSystemView.compareAsWorkspaces to compare your
workspace to the stream. That can get you a list of different baselines.
Then you could compare baselines to get the changesets within the
baselines.

This should be effective for your general case where your workspace and
streams are similar; however, you could potentially hit performance issues
if you are comparing two vastly different targets.

Also, just a small technical correction. When there are multiple baselines
outgoing on the same component, and you do a 'deliver all', under the hood
you are not delivering 'multiple' baselines to the target. You are
delivering the top-most baseline that builds ontop of the ones below it.
