I have a Visual Studio add-in which opens a modal WPF window. My problem is that the first time round, it takes 4 seconds for the window to appear - a clear disservice to the client. So I'm wondering -- is there a way to optimize this away? Some kind of nifty code to preload the PresentationFramework (or whatever is slowing the thing down) when the add-in starts, rather than when it is actually used?
