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

EncompassSettingsExport.GitWriter.cs の 52 行目と Program.cs の 71 行目から始め、続いて Repository のセットアップと repo.Branches.Count() の結果を調査します。説明されているプライベートリポジトリに対するブランチ作成の試行を再現し、既存のブランチが列挙されるか、また CreateBranch が成功するかを確認します。プロジェクトに回帰テストが用意されている場合は、該当する失敗または修正を回帰テストとともに記録します。
