 In most cases, you can use C++/CX to create Windows Runtime. However, sometimes you have to use the WRL. For example, when you create a media extension for Microsoft Media Foundation, you must create a component that implements both COM and Windows Runtime interfaces. Because C++/CX can only create Windows Runtime objects, to create a media extension you must use the WRL because it enables the implementation of both COM and Windows Runtime interfaces.
 
 > [!NOTE]
-> Although this code example is long, it demonstrates the minimum that's required to create a useful Media Foundation transform. You can use it as a starting point for your own custom transform. This example is adapted from the [Media extensions sample](http://code.msdn.microsoft.com/windowsapps/Media-extensions-sample-7b466096), which uses media extensions to apply effects to video, decode video, and create scheme handlers that produce media streams.

It demonstrates how to enumerate webcam devices and work with local scheme handlers, and demonstrates additional media effects that work on both individual photos and streams of video.
