Transition error when checking-in work item for VS2015

I faced same issue while check in from visual studio.

Change the related work item as associate instead of resolve from visual studio solved my issue.

enter image description here

I had this when checking in an associated work item and flagging the item as resolved. So

  1. Work item in in progress
  2. Check in with this work item marked as resolved
  3. Work item is updated to ready to test


the work item can't move into the new state as it needs additional information. In my case TFS is set to assign the bug back to the person that raised it. It was such an old bug that the person raising it had left the company and doesn't exist in TFS - hence the error.

Moral of the story - fix bugs quicker.

In my case, I was forced to do the Associate since I got the error message. When I went into the Work Item in VSTS I manually resolved it and it prompted me to set a required field. Were that required field set, the Resolve from Visual Studio would have worked.
