Assigning users to tasks in Visual Studio Team Services
In VSTS, if you do not see the user in the AssignTo drop down list to assign a user to a project Task, you just need to take a few more steps.
I don't see the user I want to assign the task to, in the assign to dropdown. I only see myself
all you need to do, is type a few letters of the person you want to assign the task to, in the dropdown box. You will see a little search magnifying glass
if you click the search magnifying glass, you will see the list of users in your VSTS domain.
In the Assign To dropdown list of a work item, it shows a list of most recently used users.
Because you have just joined VSTS and never assigned work items to others, you could only see yourself in the dropdown list. To assign your work item to your friends, you could search his username at Assign To textbox.
