You need to install TEK 3.0 to get it work in Visual Studio 2012. We have two versions:
- TEK 2.4.2 supports only VS/TFS 2010 and it is free
- TEK 3.0 supports VS/TFS 2012. You can download the trial version from here: http://ezien.com/en/download-tek-workitem-2012/
After click on "Copy Hyperlink to clipboards" or on "Copy workitem hyperlinks as HTML table" you may notice that "Paste" option is disabled.
TEK workitem generates HTML formatted text. Paste will be disabled in plain text controls or applications like notepad.
Try to paste TEK hyperlinks in an HTML control like work item "History" field or applications like Microsoft Word,Excel, Outlook, Lotus Notes, etc
