In TFS 2010, you can create and modify link types by using Process Editor, a power tool for Visual Studio. This tool is not supported. For more information, see the following page on the Microsoft Web site:
Team Foundation Server Power Tools April 2010.
For more information, you can refer to TFS Power Tools help: from Start->All Programs->Microsoft Team Foundation Server 2010 Power Tools->help. You can refer to
Edit a Process Template|Managing Link Types
In TFS 2010, you can use a .xml file like
<?xml version="1.0" encoding="utf-8"?>
<LinkType ReferenceName="System.LinkTypes.Dependency" ForwardName="Successor" ReverseName="Predecessor" Topology="Dependency" />
and modify it like this:
<LinkType ReferenceName="MyLinks.LinkTypes.MyLink" ForwardName="My Successor" ReverseName="My Predecessor" Topology="Dependency" />
NOTE: It is important to change the namespace from “System.” To “MyLinks.” (or some other name), because “System.” Is a protected namespace
Run witadmin.exe importlinktype to import the link type file to your collection, then go to your Team Explorer and select Refresh, or close and reopen your Visual Studio.
It is not required a VSIX package.
