I've been away from blogging for a loong time so have some catching up to do. I spent most of last year building out the new Dallas Microsoft Technology Center while delivering customer engagements and working on a few side projects. The MTC build out...

This week is shaping up to be a big week for the Dallas MTC. Monday we have our official launch party where we expect 285 attendees from Micrsosoft and partners (we've been operational since 10/6 but we're now making it official). Then Tuesday thru Thursday...

It's been over a year since I last blogged over on yassers.com. I'm trying to get back into it now and will move my blog back here to MSDN blogs. I know what you're thinking: "he moves around too much" and I agree with you :-) Not only am I moving my...

I've moved my web site and blog to yassers.com. The blog is at http://blog.yassers.com . Some of the more recent entries on this blog (the ones included in this blogs current RSS feed) are duplicated there as well.

I now work as a Technology Architect at the Microsoft Technology Center in Austin which is part of the Microsoft Sales org. In this role I help customers understand how to architect solutions to their business problems/needs using Microsoft technologies...

On Saturday 6/17 I boarded a flight from Seattle to Austin and I didn't have a return ticket. You see, for family reasons I moved to Austin and joined the Microsoft Technology Center . The goal of the MTC is to help customers map their business problems...

Last week we put up a sample named WCF RSS Toolkit on wcf.netfx3.com and I posted a sample service using it here . Since I wrote most of the toolkit’s code I thought I’d talk a bit about its goals, design and the future. There were two primary goals for...

Mark is looking for some sample code for the recently released WCF RSS Toolkit . I've put the readme up here . I won't repeat the whole readme here but here's a peek at the programming model. There are several shortcuts for feeds from databases and feeds...

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 first step was to make it easier for developers to build...

I came home today to find a large box waiting for me; it's my new iMac G5! This is the 20" intel dual core version and it's absolutely stunning. Now I must admit that this is my first Apple computer. My first computer was a Texas Instruments TI 99/4A...

Recently I've been getting lots of questions about moving large files (or lots of data) between a WCF service and client. The question comes in multiple forms, e.g. How do I send a file that's many GB in size from the service to the client? Should...

A Common a State Machine Objects that deal with communication, e.g. sockets, usually present a state machine whose state transitions relate to allocating network resources, making or accepting connections, closing connections and aborting communication...

This is a document I wrote a while ago and has been sitting around waiting to be published. Well, it finally is! Enjoy.

We have a few open positions on the Indigo (WCF) team for people who want to change the world. In this role, you would get the opportunity to really change how millions of developers write distributed applications (if you're a distributed app developer...

Most WCF developers won’t interact directly with channels or have to think about them much. 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...

For the past 5 months or so, I’ve been working on the WCF Core Communications team (with Kenny , Matt , and Steve ) where we focus on WCF transports and hosting features. In this period, I’ve learned a lot about the WCF channel model and I’m still learning...

Don Box , Chris Anderson , Anders Hejlsberg and Scott Guthrie did a 40 minute demo in Jim Allchin's keynote this morning. The demo started showing off the new Language Integrated Query or LINQ technology. Anders and Don wrote an app to query the list...

This morning, I flew out to LA for PDC. The plane landed around 12:15PM, nice and early. The ride to the hotel was mostly uneventful until we got to downtown and I noticed all the traffic lights were flashing red and drivers were confused at every major...

I've been thinking about Indigo versioning a lot recently. Basically there are three axes: 1. Versioning of protocol implementation: Say Indigo v1 implements WS-SomeProtocol v1, how do we go about that implementation so that when WS-SomeProtocol v2...

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...

I'm currently reviewing the docs for Whidbey version of ASMX (ASP.NET Web services). What are the top 1 - 3 ASMX docs topics that you'd like to see improved? I'm enabling comments for a while so you can reply to this. I'm sure I'll have to turn them off...

My blog has recently been subjected to "comment spam" so I'm disabling comments again. It's a shame because I love to hear your opinions/questions but I have over 300 spam comments just in the last week.

I just came across a statement made by a prominent industry figure about how WS-* is becoming so complex that it is not practical to implement a WS-* architecture with no tool/stack support. Well, what's wrong with relying on tools/stacks? Isn't that...

My VS Connections talk's slides and code are available here .

There are a couple of features in .NET 2.0 (Whidbey) that help solve the problems of dealing with large data. The two main issues with sending large data in Web service messages are: 1. working set (memory) due to buffering by the serialization engine...
