Couple of weeks ago I got a paper copy of book Pablo Cibraro, Kurt Claeys, Fabio Cozzolino, Johann Grabner - Professional WCF 4: Windows Communication Foundation with .NET 4. This book has not a lot of pages, just about 400. Really, I don’t remember when I saw so thin book about some technology. But maybe this book has not a lot pages, but a lot of interesting themes.

First chapter is patterns and principles of SOA applications. This is the best chapter in this book. When I was reading this chapter I saw that authors have a lot experience of creating applications with Service-oriented architecture. Authors described all possible architecture principles, with which you can create SOA applications. And they did not limit themselves to the principles that are possible with WCF. I think that this chapter is “must read” for all developers, it is doesn’t matter what technologies you are using: php, java or .net. And this is good luck that Wrox published this chapter online: Design Principles and Patterns. It is about 30 pages, so read it right now.

At our product we have a client Silverlight part and server-code part, which contains a lot of WCF methods. We don’t use ASP.NET Compatible mode, because we want to leave an opportunity to deploy server part to server without web-server role (without IIS). Really, I don’t know why we chose this way, because all of our installations at current moment are on IIS. But we have what we have, so we haven’t ASP.NET Compatible mode, and as an expected result we can’t get HttpContext.Current instance at server WCF methods. One of WCF Service is a RESTful service, which at his methods returns report files, so it can handle GET-queries from browsers.
