[Rpatil3g]

LibGit2Sharp.PullOptions options = new LibGit2Sharp.PullOptions();
options.FetchOptions = new FetchOptions();
options.FetchOptions.CredentialsProvider = new CredentialsHandler(
(url, usernameFromUrl, types) =>
new UsernamePasswordCredentials()
{
Username = _gitCredsUser,
Password = _gitCredsPassword
});

            // User information to create a merge commit
            var signature = new LibGit2Sharp.Signature(
                new Identity(_gitUsername, _gitEmail), DateTimeOffset.Now);

            // Pull
            Commands.Pull(repo, signature, options);

I am using LibGit2Sharp dll of 0.26.0.0, from last few days I am getting "failed to parse supported auth scheme" error while doing git pull. My git repository is on GITHUB. I am sure there might security related changes done on github side. that's why this error come.
