Our company is still using IE 8 in all projects. After our team upgraded from TFS 2010 to TFS 2013, the TFS 2013 dashboard is looking good.
However, one interesting part is that when I click the Charts on IE8, it shows the following error:
TF401209: The chart requires capabilities which are unsupported on the current web browser
When I use Chrome, it is working perfectly.
I don’t feel surprised to see this error because it makes me remember when I installed VS 2013 Preview version, IE 10 was required, but finally it is not required for VS2013 RTM.
In the meantime, in order to fully use TFS 2013 dashboard, forget about IE8 and use Chrome if your company is still using IE8.
