I don't know you guys, but here in my machine, the Microsoft Visual Studio Xaml UI Designer is a pain in the a**.
When I realize the Xaml code is slow, every key press is very slow, I go to the task manager > processes and I see 3, 4 or 5 XDesProc.exe processes running, each one consuming about 90.00k memory.
This happens to you too?
