Strange behavior of "Assigned to" field in TFS 2012

Question

When I create a bug on TFS 2012 and somebody marks it as resolved and check the code in (typing the item id), the field "Assigned to" gets my name instead of the developer's name (who did fix the bug).

Why does this happen?

Using TFS 2012, Agile template (no modifications)

Answer 1

Because you opened the bug, the default workflows assign the bug back to you to verify and close it once it has been resolved.

If you need a report with the person who marked the bug as resolved (usually the developer on check in) you can use the "Resolved By" column from "Column Options" dialog of the TFS Query.
