If you've tried to deploy Windows Communication Foundation (WCF)  in a production environment the odds are you have come across this error at one point or another: This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection. Parameter name: item It is one of those lovely errors that should have been gumped down before it made it into production code but for some reason the developer who wrote it thought they'd sound smarter if they obfuscated the problem to confuse everyone.  No fear, I'm hear to clear this up...

I will visiting the Lower Alabama .Net User Group on May 27th presenting a talk on Windows Workflow Foundation.  Here are the details: Location:  Office Mall South  3100 Cottage Hill Road  Building 3  Mobile, AL 36606Time:  May 27th, 2008, 6:00 PM Topic: Introduction to Workflow Foundation Foundation Scenario: Your boss gives you a task with fairly complicated business rules one day at work. You spend weeks coding it and as soon as you get done he/she informs you the business rules have changed. Your first thought is to lash out at your boss because this is a major change. Instead...

Dustin, sorry, but I had to share this video with everyone because I saw you eat at least twenty pounds of  tuna fish over the course of the MVP Summit.  Consider it a farewell tribute since you joined Microsoft.  The video was taken at the EMP museum in Seattle, WA on April 16th, 2008.

Thursday night we gathered at Kell's Irish Pub and Restaurant one last time before heading home from Seattle.  There was an unofficial count of about 75 of us that gathered for food and chatter.  It was certainly a lot more than last year and we had a blast.  Thanks to everyone that came out and we'll try to do it again next year!

At the MVP Summit 2008 I didn't take a large amount of pictures but I did take a few.  You can view them here. http://flickr.com/photos/keithelder/sets/72157604626519285/

For some reason, and I can't explain it, creating a backup of my laptop has been weighing on my mind.  I haven't gotten my Windows Home Server up and running yet thus I'm having to do it by hand right now.  Since I am about to take a cross country flight I decided to take a snapshot of things before heading out.  My tool of choice is RoboCopy which is included with Vista.  So I don't have to stare at the robocopy help screen again here's how I backuped up my files to my external Western Digital 400GB My Book drive using RoboCopy. ...

I was writing a test earlier today  trying to play nice with the red first green later crowd.  When I first wrote my test it showed red.  It didn't work, this was good.  I went in and wrote what I thought was "green" code.  I ran it and whoops I didn't mark my dummy class public so the XML serializer blew up.  My test failed again.  I fixed that quicly and ran the test again and it failed again!  I looked at the message and this was staring me in the face. Assert.AreEqual failed. Expected: <system.xml.serialization.xmlserializer> Actual:       <system.xml.serialization.xmlserializer> Yah.  I'm at a loss too.  Doesn't this test...

Coming up with a name for something is one of the hardest things to do.  A name says the intent, can lock you into certain genres and much more.  I need your help in naming my up and coming podcast show.  Before you cast your vote here is the intent of the show. A show with a Southern Flavor telling tales and stories about technology that is available today from the perspective of those who have gone through the learning curve of the technology and are ready to tell their story in a simple and easy to understand manner. There are three...

Next week is the MVP Summit.  This is one of the events I have looked forward to the most since I was fortunate enough to go last year.  MVPs from all across the world descend upon Seattle and Redmond during this week to meet with MVP Leads and product teams from Microsoft.  Someone asked me what it is like and I described it as hanging out in the speakers lounge 24/7 at a gigantic conference.  Sunday evening is Party with Palermo.  Jeff's parties have become a staple event for everyone to gather and have fun.  Monday we'll kick off...

Never Installed The ClickOnce Of Witty? If you've never installed the previous version, no worries just click the link below to download and install the app. Download here:  http://keithelder.net/software/witty/witty.application Previous Install If you happen to be running the ClickOnce version of Witty I created, the new update I just put out is going to break the automatic update.  If you are running the following version of Witty, via the ClickOnce install I published, you will need to uninstall this version to upgrade to the latest release. Why? Answer:  Because my idiotness knows no boundaries and I deleted the certificate I had originally created when I deployed...

UPDATE: This post was posted on April 1st and thusly is an April Fool's.  It was posted about 5.5 hours after another post that was also an April Fool's that started the whole thing.  Maybe now the emails and phone calls will stop.  :) I spent weeks writing up the previous article I posted to this blog this morning about how I had joined the silver card carrying members club at Apple.  Congratulations poured in from the community congratulating me on my accomplishment.  My Macbook Pro and iPhone were already on order as well as my wife and I were...

UPDATE:  This post was posted on April 1st, and thusly is an April Fools post as is the follow up post.  Maybe the phone calls and emails will stop now. :) Today publicly, I am announcing for the first time that I will be going to work for Apple Computer.  It is no doubt monumental news that I've been holding back until the final contracts and NDAs were signed.  This evening everything was finally settled. You are probably wondering what in the Wide Wide World of Sports is going on!  What would Apple want with someone who refers to himself...
