I have added an extra event handler to the TFS Event Handler (Prototype), and this makes two.
Assigned To Handler
The Assigned to handler send a users an email when a work item is assigned to them unless they did the assigning themselves.
Reassigned Handler
The reassigned handler send an email to a user to whom a work item used to be assigned, letting them know that they no longer have that piece of work in their list.
These handlers are easily added to a current deployment and are packaged together. You will need to update the version of your prototype deployment by downloading the latest version, but it does fix a number of found bugs.
Once you have the new version, download the Assignment Handlers rar file from the release page and extract them into the "c:\Program Files\RDdotNet\RDdotNet Team Server Event Handler (Prototype)\EventHandlers\WorkItemTracking" folder.
Stop the "TFS Event Handler (Prototype)" service and open the "RDdotNet.TFSEventHandler.exe.config" file with notepad.
if you want the AssignedToHandler to work ad the following line:
<Handler type="RDdotNet.TeamFoundation.WorkItemTracking.AssignedToHandler"
assemblyFileName="RDdotNet.TeamFoundation.WorkItemTracking.Assignement.dll"
assemblyFileLocation="~\EventHandlers\WorkItemTracking\">
</Handler>
And if you want the Reassigned handler to work add the following line:
<Handler type="RDdotNet.TeamFoundation.WorkItemTracking.ReAssignedHandler"
assemblyFileName="RDdotNet.TeamFoundation.WorkItemTracking.Assignement.dll"
assemblyFileLocation="~\EventHandlers\WorkItemTracking\">
</Handler>
If you want both to work...then add both...easy.
