I, Carlos Figueira, work at Microsoft as a Senior Software Design Engineer in Test in the Windows Communication Foundation (WCF) team. I've worked in different parts of the product, including serialization, service model, messaging framework and the Silverlight version of WCF.
This blog is mostly about issues I've seen customers facing with WCF (both from the WCF Forums and other customer interactions), and here I try to show, most of the times with code examples, how those issues can be solved. I've also posted about issues I've had while working that I think may be useful for others as well.
My other interests include sports and food (see my other blog at http://carlosfigueirafilho.wordpress.com/). To get updates from this (and the other blog) you can use an RSS aggregator, or follow my twitter account (which I use mostly to announce new blog posts) at http://twitter.com/carlos_figueira.
