WCF services getting errors when hosting in IIS
Wednesday, June 04, 2008 11:42 AM
This post is more for my own records than anything and I have been meaning to write this down for some time. Problem: Had a WCF Web Service that was being hosted in IIS. Worked in dev and test fine. Moved to prod and bang, I get the following error: This collection already contains an address with scheme http. There can be at most one address per scheme in this... Read More...

MCTS in WCF
Sunday, April 20, 2008 6:55 PM
So a little while ago, I mentioned that I did a WCF beta exam for a Microsoft Certified Technical Specialist. Its been a long time since I did that and I had kinda forgotten about it, but today I received the good news that I am now a MCTS in WCF! WooHoo! I really thought I had bombed that exam due to the very little prep that I had done, but fortunately that... Read More...

WCF & ASP.NET Role Provider
Friday, February 08, 2008 3:08 PM
So I was talking to Shea Strickland a relatively new starter in readify who is doing some WCF work and asked about the role provider support in WCF. He pointed me to an article by Dominick Baier who mentioned that the RoleProviderPrincipal in WCF will actually cause a database call each time an IsInRole check is performed. After some experimentation, this was... Read More...

WCF Beta Exam
Sunday, December 02, 2007 8:17 PM
I took the opportunity to sit the WCF Beta exam a few days ago and I must say, it was very hard. Being beta, I don't find out the results until about 8 weeks later, but I reckon I didn't fare too well. I did book the test a little impulsively, however I saw the opportunity to do it, and only had a free day to do the test that was a few days later than when I... Read More...

Blog Article On a recent project we had the requirement to produce a web application as part of the main deliverable, but also to provide a services layer or implementation, that will allow external clients within the same organization to interact with the underlying system.

WCF and Concurrent usage throttling
Wednesday, June 27, 2007 12:37 PM
Have a requirement to interface with a legacy system that exposes a set of web services. The legacy system is not terribly fast and there are concerns by the client that it cannot handle excessive load. It seems to handle the current load ok, but we have been tasked with writing a system which will interface directly with the legacy system and potentially increase... Read More...

WCF Client Performance
Saturday, April 21, 2007 6:22 PM
One of the easiest performance traps when using WCF services is constant creation of new client proxies when accessing those services. In WSE land, this was common place: MyProxy prox = new MyProxy(); prox.CallServiceMethod(); For example, you might have a class with some instance methods, and in each method, instantiate a proxy, call the service method, life...

I am running this within Vista, although it should be "similar... Read More...
