问题如下:
We were unable to establish the connection because it is configured
for user olduser@old.com but you attempted to connect using user
newuser@new.com. To connect as a different user perform a switch user
operation. To connect with the configured identity just attempt the
last operation again.
需要把旧账号的信息清除掉:
1.进入vs2013的安装目录D:\vs2013\vs\Common7\Tools\Shortcuts
2.以管理员身份打开快捷方式Developer Command Prompt for VS2013
3.输入devenv /resetuserdata
4.重新打开软件即可
