Have you ever wondered if the default YouTube application can be replaced? With tight system integration to the level where it has its own URI scheme registered, it seems like it’s a sealed deal and developers can’t do anything about it. What developers don’t know is that it is possible to fully replace the default YouTube application as long as you take it’s identity. Apparently Windows Phone OS recognizes applications by IDs only.
Windows Phone 7 comes with built-in support for YouTube. The system has a dedicated URI scheme registered for it, and I talked about it a while ago. It is pretty cool if the developer knows the URI scheme so that the application can be initiated from inside another application, but it is even cooler to disassemble the default YouTube application itself and attempt to integrate Microsoft-built capabilities in your own application.
