In github I can view a commit and view all the releases it was part of.
I am trying to do something similar with LibGit2Sharp. I can find a commit and I can find a release, but I can't see how to tell if a commit was in a release or not.
Is this possible, if so how?
A Release is a GitHub concept. It's built on the git concept of a Tag and enriched with a styled Release Notes and downloadable assets.
From the LibGit2Sharp perspective, what you're after is finding all the tags that point to a specific commit.
The SO question What's the fastest way to find Tags pointing to Commits? deals exactly with this.
