The WPF Performance Suite is described here:
http://msdn.microsoft.com/en-us/library/aa969767.aspx#installing_the_wpf_performance_suite
-> how can I install it on Windows 8?
(the Windows 7 SDK can't be installed and the Windows 8 SDK contains Performance tools such as GPUView but not the WPF profilers "Perforator" and "Visual Profiler".
I googled several hours for it but didn't find anything.
