Checking out a branch

[amlwwalker]

How do I checkout a branch?
I can open a repo, create a branch, stage changes, commit changes, but what I need to do is checkout an existing branch.
How do you do that?

You can use Repository.CheckoutTree() to checkout the files. If by "checkout a branch" you mean switch to that branch, you will also need to update HEAD, e.g. with Repository.SetHead()
