}
catch (Microsoft.TeamFoundation.Git.Contracts.GitPermissionDeniedException ex)

In some cases, an invalid operation performed on the Git repository may result in this exception. For example:

    var repoPath = "https://dev.azure.com/organization/project/_git/Repository";
    var repository = new GitRepository(repoPath);
  
    // Attempt to clone repository into an existing directory
    repository.Clone("C:\\Existing\\Directory");
