Trouble with work item links and model elements in Visual Studio 2010 Ultimate?
Why aren’t linked model elements appearing in my work items?
In Visual Studio 2010 Ultimate, links between model elements and work items travel in one direction only, from the element to the work item. This means that when you link an element to a work item, the linked element does not appear in the work item. To enable bidirectional links, install the Visualization & Modeling Feature Pack. This means that when you create a link from a UML model element to a work item, a link from the work item back to the model element will also be created. To see this link in the work item, open the work item and refresh it manually.
Alas, bidirectional links are still not created automatically if you link a layer diagram element to a work item, so instead, create the link to the layer element from the work item. For more information, see How to: Link from Work Items to Model Elements.
Why aren’t links to work items removed from model elements when I delete the links from the work item?
You must delete the link manually from the element. When you remove a work item link from a model element, the link from the work item to the element is also removed. However, when you remove a model element link from the work item, the link from the element to the work item is not removed. For more information, see How to: Link from Model Elements to Work Items.
