Error encountered while cloning the remote repository with VS 2015 Update 3 (TFS 2015 Update 3)
提问by Raghu
I have recently upgraded to VS 2015 (Update 3) on the client side and TFS 2015 (Update 3) on server side. The Git operations worked for a while, then I started getting following error when trying to clone a git repo:
我最近在客户端升级到 VS 2015（更新 3），在服务器端升级到 TFS 2015（更新 3）。Git 操作工作了一段时间，然后在尝试克隆 git 存储库时开始出现以下错误：
Error encountered while cloning the remote repository: An error occurred while sending the request.
Inner Exception:
The remote server returned an error: (401) Unauthorized.
Inner Exception:
No credentials are available in the security package
But I can navigate to repo in the browser without any problems. Then, I figured this may due my client side settings. I tried removing the VS cache as well as TFS cache. Nothing worked. When I used Fiddler, it should following information:
但是我可以毫无问题地导航到浏览器中的 repo。然后，我想这可能是由于我的客户端设置造成的。我尝试删除 VS 缓存以及 TFS 缓存。没有任何效果。当我使用 Fiddler 时，它应该遵循以下信息：
It revealed following information:

With this information, I searched for libgit2*.* file in my visual studio folders. I found several instances of LibGit2Sharp.dll. All of them have same version (0.22.0.0) but one instance had the version 14.0.25029.0. I tried copy the version 0.22.0.0 over on top of 14.0.25029.0. But visual studio complained about it during launch. The folder with 14.* version is found in "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions" folder and it contains several dlls that start with "Microsoft.TeamFoundation.". All of those dlls have the version: 14.102.25521.0 (which is what I found in the fiddler trace).
有了这些信息，我在我的 Visual Studio 文件夹中搜索了 libgit2*.* 文件。我发现了 LibGit2Sharp.dll 的几个实例。它们都具有相同的版本 (0.22.0.0)，但一个实例的版本为 14.0.25029.0。我尝试将 0.22.0.0 版本复制到 14.0.25029.0 之上。但是visual studio在发布期间抱怨它。14.* 版本的文件夹位于“C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions”文件夹中，它包含几个以“Microsoft.TeamFoundation.”开头的dll。所有这些 dll 都有版本：14.102.25521.0（这是我在提琴手跟踪中找到的）。
Looks like I am at the right problem area but not sure how to fix the error.
看起来我在正确的问题区域，但不确定如何修复错误。
Any ideas?

After struggling with the above problem for a week, I posted the question today. But right after posting, I landed on a solution.
在为上述问题苦苦挣扎了一个星期后，我今天发布了这个问题。但是在发布后，我找到了一个解决方案。
It has nothing to do with visual studio/tfs upgrade. I must have entered wrong tfs credential information (while checking remember me box). With remember me feature, the team explorer never gave me a chance to correct the credential information and probably kept using stored wrong credentials. Here is what I had to do to correct the issue:
它与 Visual Studio/tfs 升级无关。我一定输入了错误的 tfs 凭据信息（在选中“记住我”框时）。使用记住我功能，团队浏览器从未给我机会更正凭据信息，并且可能一直使用存储的错误凭据。这是我必须做的来纠正这个问题：
- Control Panel\User Accounts\Credential Manager
- Remove any tfs related credentials.
- Launch visual studio
- It will now prompt you for tfs credential information.
- 控制面板\用户帐户\凭据管理器
- 删除任何与 tfs 相关的凭据。
- 启动视觉工作室
- 它现在会提示您输入 tfs 凭据信息。
Problem solved.
问题解决了。
