Cannot login to Bitbucket from Visual Studio 2015 Community Edition

[Daniel Goss]

i am getting the Following error when i try connecting my VisualStudio 2015 Community Edition to My BitBucket Account: Unknown Error (could not load type 'system.valueTuples'2' from assembly 'System.ValueTuple, version=4.0.3.0,Culture=neutral,PublicKeyToken=cc7b13ffcd2ddd51'.). check logs for more info

I can login normally from any browser and create and manage my repositories OK. I have installed the Bitbucket extension in Visual Studio already. Just get this problem when trying to connect through VS 2015. I have noticed this seems a common problem ??

Please help.
