Apps are going fullscreen instead of windowed

[YalekW5435]

For some odd reason when visual studio updated to its most recent version, apps are not staying windowed. They are forced to go fullscreen, even if the desktop resolution is more than the app's resolution. the mWidth and mHeight variables in PopApp and AppBase are not being registered as a window width or height. Instead, the app is fullscreen and is adjusting and compensating for the resolution set in the App Constructor. mWidth and mHeight do not register window values. It doesnt matter what renderer API I use, all the apps are fullscreen. No more windowed. And I cannot for the life of me figure out what happened...
