As yo know Team Foundation 2013 has introduced Tags feature and I have been able to work with it using the web interface of the Team Project. but I was not able to access and set tags for work Items from within Visual Studio 2013. I just can add the Tags column to the query columns.
Is there a way to specify Tags and filter based on them for Work Items from within Visual Studio just like how it works in the web version of TFS?
Aram,
Both Visual Studio AND TFS should be upgraded to "Update 2".
After you upgrade both, "Tags" should be available in work items also in Visual Studio.
To use tags in queries and filer data you need the Visual Studio 2013 Update 2 RTM installed on premise.
