Book on WCF for FW 3.5

[ugh3012]

I need to learn WCF. The book has to be for someone who knows nothing of it and it is a step by step to build one. The company I work for still uses VS 2008; therefore, the book has to be an older print for FW 3.5. I found many books, but many of then are for FW 4. I dont want to order a wrong book again.
