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.

Reproduction steps

Expected behavior

git pull should work without error.

Actual behavior

Version of LibGit2Sharp (release number or SHA1)

0.26.2

Operating system(s) tested; .NET runtime tested

windows 10

Commencez par l'appel montré à Commands.Pull et sa configuration de FetchOptions/CredentialsHandler dans LibGit2Sharp 0.26.2, puis reproduisez l'échec d'authentification sous Windows 10 avec GitHub. Comparez les schémas d'authentification pris en charge concernés et vérifiez qu'un pull utilisant les identifiants indiqués se termine sans l'erreur d'analyse.
