调研方向

从 Repository.Clone API 开始，比较 libgit2sharp v0.26.2 和 v0.30.0 之间的证书验证行为。在受影响的环境中使用 Windows 11 和 .NET Framework 4.7.2 重现该故障；当内部仓库可以在不出现 SSL/TLS 验证错误的情况下完成克隆时，即表示完成。

描述

I recently updated libgit2sharp (v0.26.2) to the latest v0.30.0.

Some of my product users are located in Taiwan, some are in China, and some are from Europe and the United States.

Before the upgrade, the company's internal repository could be accessed normally through the Repository.Clone API.
(URL and WorkDir only, no other options)

After the upgrade, users located in China will fail and get an error about SSL/TLS being unable to verify, as shown below.

We tried to troubleshoot other network issues and confirmed that all users were on the same OS version and supported TLS 1.2/1.3 only.

And do cross comparison with git CLI (git v2.43.0).

Everyone can download normally through the CLI, and will not encounter SSL/TLS verification errors when using libgit2sharp v0.26.2.

Only users located in China will encounter SSL/TLS verification failure in libgit2sharp v0.30.0.
