Has it already been brought to your notice that the rending of XAML page is very slow in VS?
I use VS 2015 CE; got Intel i7, 8 GB RAM. Is this not enough?
When I change the XAML code and save, VS kind of freezes, blocks further editing, until the XAML is validated and rendering of XAML is done.
Can you please do that in separate thread, so that we can continue typing in the code and save it often too?
