Adding custom file extension associations

Question

I want to add my own custom file extension into the win 7 registry. And I also want to add a right click option "Play with xPlayer" for this extension.

I want to use it in my C# application. How can I do it using the registry?

MSDN has extensive documentation on how to work with file extensions in the Registry. Start with these articles:
