-description
Gets or sets the size that the app launches with when the ApplicationView.PreferredLaunchWindowingMode property is set to PreferredLaunchViewSize, except in cases where the system manages the window size directly.
-property-value
The size that the app launches with when the ApplicationView.PreferredLaunchWindowingMode property is set to PreferredLaunchViewSize, except in cases where the system manages the window size directly.
-remarks
This property only has an effect when the app is launched on a desktop device that is not in Tablet mode (Windows 10 only).
For the very first launch of an app the PreferredLaunchWindowingMode will always be Auto and the ApplicationView.PreferredLaunchViewSize will be determined by system policies. The API applies to the next launch of the app.
