Strange issue. Just noticed, but it was bugging me for a while, perhaps since installing Update 3.
When closing VS and opening project again (by double-clicking .sln file), the opened windows persists (all opened .cs files to example).
If I have any .xaml opened, then solution is opened without a single opened window:
It's a very minor, but pretty annoying.
