Visual Studio 2017-TFS 2017-“对象引用未设置为对象的实例”

Question

I installed a new TFS 2017 on a fresh Windows 2012 R2 Datacenter server. Than I created a project with a Git repository in it. Now I want to use this inside of my visual studio but as soon as I choose "Connect" on the specific project, I got the "Object reference not set to an instance of an object" message. After that, my Team Explorer looks like this:

How can I fix this problem? I already tried to delete the Visual Studio and TFS folders in my local AppData cache directory - nothing changes. I can't find any log files to check the problem, so I hope someone here can help me with that...

Edit : It works in Visual Studio 2015. But I want to use it in 2017... any advice?

Edit 2 : Tested on 2 other systems by myself and two of my frieds tested it too - all the same problem. But if we use the "Clone in Visual Studio" link from the TFS Web view - we got a "Failure when receiving data from the peer" error.

Answer 1

Works since the last VS2017 update... So it was a problem from the Git integration in the VS2017. Also on any other PC it works now with this update and without any other changes.

Answer 2

To narrow down the issue your could create a team project both from the web & from team explorer .

Moreover, since it works in VS2015, fail with 2017. Also suggest you to update your VS2017 to latest RTM version and try again due to this error: Cannot connect to VSTS and TFS from VS 2017 RC
