WCF Custom Channel Ecosystem

Back in January, a few of us on the WCF team kicked off a side project dubbed “the channel ecosystem project”. The goal is to create a community and an ecosystem around WCF custom channels.

The Service Model, WCF’s programming model, provides abstractions that layer on top of channels to give a “method and typed parameters” programming model. However, many developers will want to write custom channels for the reasons I mentioned in my previous…

It’s fun being a test engineer on Indigo

Recently, I spent a few days writing test cases for the MetadataExchange endpoint feature in Indigo. This started as a way to help out our overly thin-stretched test team so that we can get this feature in Indigo Beta1. It has since turned into an educational experience for me. It’s increased my, already tremendous, appreciation…
