The architecture we saw last time is actually a nice solution to the original web service problem . We did end up changing the security mechanism, transfer mode, message arrangement, and transport policy through a couple of different configurations in...

In this series, I've gone through one set of problems that we encounter with buffered transfers , and a different set of problems that we encounter with streamed transfers . Each mode has its advantages, although it would be really nice if we could combine...

To answer a question I've heard a couple times now, WCF is almost entirely written in C#. And, almost every line of that C# is managed, type-safe, and verifiable. There's very little in WCF that you can't do with just the Base Class Libraries in the 2...

Yesterday, we looked at an architecture change from a buffered transport strategy to a streamed transport strategy . Making this change improved the scalability of the service by eliminating the large memory allocation for each concurrent connection....

Continuing with the same seemingly simple web service scenario as before, last time we saw an obvious problem and solution with our proposed architecture. The problem I want to talk about this time is a little more difficult to solve. Suppose that...

Yesterday I introduced a simple web service scenario along with one way to solve the scenario using WCF . If you actually tried to use that architecture though, you would quickly run into a couple of problems. The first problem is common and I hope...

I've been noticing the large number of smart quotes littering my previous posts so I went back to take them out. Properly arrayed quotes are a nice addition in printed text, but they're a real choking hazard for browsers. Now I just need to find out what...

Now it's time to start digging a little deeper into the guts of WCF. I decided to make up a simple scenario that just happens to exercise lots of WCF technologies. Since I'm not going to be writing about the various WS-Whatever standards for a while,...

After a quick diversion to introduce WCF, I wanted to go back and finish introducing myself. I promise that this is the last introductory post in my queue. WCF has so much to talk about that I can fill every day between now and when Vista comes out just...

When I say that I work on the Windows Communication Foundation team, a lot of people ask me the deep and piercing question: "What's that?" Sometimes I try to prompt them with the former codename 'Indigo', figuring that they just haven't heard...

Hey everybody, I'm Dr. Nicholas Allen, and I'm a Program Manager at Microsoft on the Windows Communication Foundation team (formerly known by the much hipper name 'Indigo'). For those of you that don't know what a PM does, check out the very extensive...
