Why there are no "Building Facebook App with Yii" tutorial available?

I think this is strange. Yii is so powerful and popular framework and Facebook Apps is so hot topic right now, but there are no tutorials on how to create Facebook Apps with Yii, I digged all the internet and what I found were only "Facebook App with Yii" job listings.

Maybe I’m wrong? Are there any tutorials/app code available?

You don’t need “Facebook App with Yii”.

You need "Facebook App with PHP".

That’s the reason why there is no need to create something specific for Yii because there are allot of tuts for php.

Yii is so powerful that let programmers do the job… nevertheless, there are some Yii-goers that have developed some extensions to easy that task for us:

this extension unsecure, use it carefully.
