Last week I've updated my windows from 8.1 to 10 and my Visual Studio from 2013 Ultimate to Enterprise 2015.
Yesterday I've implemented Load Tests via a Web Performance and Load Test Project. At this point I'd like to add an ILoadTestPlugin via the "Add Load Test Plug-In" option.
This does not work, as Visual Studio tells me it cannot find System.Windows.Interactivity assembly.
As this also happens in my Visual Studio 2013 installation, I think the problem is not Visual Studio 2015 related.
As the error comes from the Visual Studio IDE as an Visual Studio internal error, this is not a duplicate of "how to add System.Windows.Interactivity to my solution!
