DevBytes: BitmapAllocation

This example shows how to speed up bitmap loading and reduce garbage collection by reusing existing bitmaps.

Note that the reused bitmap must be mutable and of the same size and configuration as the bitmap you load into it. Not sure if this is clear from the video, although it is documented in the API.

BitmapAllocation in the title and View Animations in the video, whoops!

@Marc: I'm not seeing that problem, but someone else told me the same thing; maybe some YouTube bug, or a problem with the channel of the videos. Are you seeing the incorrect content in the embedded video above? Or on the youtube page linked above?
