Not seeing any branches, can't create branch

I am running into the following error when i try to create a branch...

LibGit2Sharp.NotFoundException: revspec 'master' not found

The line of code that produces this error is

brnch = repo.CreateBranch(Branch)

Where Branch is just a string like "test-brnch" and repo is a Repository object i've already created.

I am checking to make sure i can see my repo here (it is a private non-local repo)

Repository.IsValid(PathToRepo)

and this returns true.

I create my repo here...

repo = new Repository(PathToRepo);

However i've noticed that when i call

repo.Branches.Count();

This return 0 even though i do have a few branches in my repo

Commencez par EncompassSettingsExport.GitWriter.cs ligne 52 et Program.cs ligne 71, puis examinez la configuration de Repository et le résultat de repo.Branches.Count(). Reproduisez la tentative de création d’une branche dans le dépôt privé décrit et vérifiez si les branches existantes sont énumérées et si CreateBranch réussit ; documentez l’échec ou la correction pertinente avec un test de régression si le projet en fournit un.
