I'm back on ASP.NET (at least more than last year :-)) - And it feels great (again) digging deep into some interesting areas around user interfaces (also WPF!!!), processes and tasks, state management, async stuff (multi threading/AJAX & JSON) and so on...

My colleague Sergey is working on a really nice package around CardSpaces. Watch his blog for updates...

I was just about to generate a client (proxy) for a WCF service on a computer (in a domain) on customer site when svcutil.exe returned the following:

Microsoft (R) Service Model Metadata Tool
[Microsoft (R) Windows (R) Communication Foundation, Version 3.0.4506.30]
Copyright (c) Microsoft Corporation. All rights reserved.

Error: Cannot obtain Metadata from http://127.0.0.1/CallahanWeb/service.svc?wsdl

If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address. For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.

WS-Metadata Exchange Error
URI: http://127.0.0.1/CallahanWeb/service.svc?wsdl

Metadata contains a reference that cannot be resolved: 'http://127.0.0.1/CallahanWeb/service.svc?wsdl'.
<?xml version="1.0" encoding="utf-16"?><Fault xmlns="http://www.w3.org/2003/05/soap-envelope"><Code><Value> Sender </Value><Subcode><Value xmlns:a="http://schemas.xmlsoap.org/ws/2005/02/sc"> a:BadContextToken </Value></Subcode></Code><Reason><Text xml:lang="de-DE">The message could not be processed. This is most likely because the action 'http://schemas.xmlsoap.org/ws/2004/09/transfer/Get' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.</Text></Reason></Fault>

HTTP GET Error
URI: http://127.0.0.1/CallahanWeb/service.svc?wsdl

The document was understood, but it could not be processed.
- The WSDL document contains links that could not be resolved.
- There was an error downloading 'http://dpc00000198.clients.eden/CallahanWeb/service.svc?wsdl=wsdl0'.
- The request failed with HTTP status 407: Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied. ).


If you would like more help, type "svcutil /?"

Seems that svcutil does not support http proxies that require authentication... After i disabled the proxy in IE's settings it worked ;-)

Looking back on 2006 ... that was a lot ... and the reason I was a bit quiet

  • Together with Clemens I wrote a message based waterfall-caching-framework which can be hooked into a web service architecture for a customer.
  • For Uwe Baumann of Microsoft Germany I wrote a localizable ASP.NET starter kit (with a discussion forum and a really nice membership administration API) for coding4fun.de.
  • I distinguished technical and architectural fires (mostly ASP.NET, Web Services and ADO.NET) in Germany, Luxembourg and Sweden.
  • Consulted half a dozen customers from several industries throughout Germany.
  • As a trainer and speaker on conferences and trainings I've bin to Germany, Poland, Denmark, Greece, Ukraine and England
    • DDD was really one of the best events out there!!!
  • Together with Stephan I organized the biggest regional software developer community event (NRW06) and connected .NET, PHP, Java and Linux developers.
  • I had an interesting fight: Me vs. Java consultant (to let a customer make a decision on IT strategy).
  • Worked together with Michael, the newtelligence crew, Microsoft's DPE in Germany and the connected systems team in redmond on a security analysis on Windows Communication Foundation (WCF) for the Federal Office for Information Security of the German government (BSI).
  • Created material and did 3 architecture gigs for Microsoft EMEA.
Hmmmm, I'm pretty sure I forgot something...

I'd like to thank everybody I worked with. May you all have a merry XMAS and a happy new year.

I just got "tagged" together with Steve, Don, Udi and Nicholas  by Clemens. So here are my five:

  1. The nickname "Lennybacon" was given to me by my girlfriend and is (probably) based on my middle name "Leonard" and the fact that I like bacon for breakfast.
  2. My surname is written without a "c" which is quite strange for most Germans (beside my certificate of birth about 80% of the official documents spell me the wrong way). The English way of spelling is because of my father who is an American and his forefathers who came from England.
  3. I started working with computers beside school and administered Novell and NT Networks.
  4. I programmed my first Windows application in 1996 using Delphi. At this time I still wanted to become a Carpenter. The only reason I did not become one is that in that company they started to drink alcohol at 8 o'clock (work started at 6).
  5. The oldest piece of a computer I own is a 15x15x0.5 inch disc with 4 MB storage. It was a present from a customer and given to me after finishing a project.

And the Oscar Tag goes to:

Michael, Thomas, Kenny, Bob and Craig

DDD (developer developer developer) is back and will be held on Saturday 2nd December at the Microsoft Offices in Reading.

It is a pleasure for that I've been voted again to speak. This time I'll present "DataAccess Layers - Convenience vs. Control and Performance?" on my own and "Decoupling Service Oriented Backend Systems [with Windows Communication Foundation (WCF)]" together with my colleague Michael.

I'm looking forward to meet Craig, Barry, Oliver, Phil, Ian and all the U.K. Community.
