Quality and reliability improvements

WPF1

- Addresses a hang when scrolling a list control where both these conditions are true: UseLayoutRounding is enabled, and The item margin is not a multiple of the rounding quantum. (The quantum is a function of the DPI scaling in effect.) - Addresses an exception "Height must be non-negative" that can occur when adding items or groups to the collection displayed by an ItemsControl. - Addresses an issue where a shared ContextMenu stops displaying after it fails to display once because its owner was removed from the visual tree.

CLR2

- Addresses rare crashes and hangs that can appear in cases where a GC occurs while another thread is in the middle of certain special paths used to invoke shared-generic code from non-shared-generic contexts.

₁ Windows Presentation Foundation (WPF)
₂ Common Language Runtime (CLR)
