Excellent Article on WCF Channel Development and WCF Framework Extensibility
This is very old news, but it's worth repeating. The highly respected WCF Sensei -- Nicholas Allen -- has an excellent article on the binding stack in WCF, how WCF is extensible, and specifically, where and how you can customize these points. I've been looking for this kind of treatment of WCF customization for some time. I really could have used it when I was struggling with building a custom interop solution for a client, but alas. Regardless, I'm noting it here for posterity and for anyone else ......

Equivalent svcutil.exe command for VS2008 Add Service Reference
As a followup to my post about serialization funkiness between WCF and Peoplesoft, I wanted to post what svcutil.exe command I used to mimic the built-in behavior of the "Add Service Reference" behavior in Visual Studio 2008. Contrary to Visual Studio 2005, the Add service reference command in Visual Studio 2008 does not use svcutil.exe, but rather it's own built-in functionality. Using a comparison reference between the two and my own analysis of the results, I came up with the following command ......

WCF: System.InvalidOperationException: Unable to generate a temporary class (result=1)
I ran across this trying to interop with a Peoplesoft web service using WCF. If you've ever worked with Peoplesoft web services, you'll know that the contracts that are spun up are just plain wacky. Arrays embedded within arrays embedded within still more arrays ... simple types represented as a complex type, like a string represented as a typeShape with a .value property ... and more goodness! Anyhow, I generated my service reference from within Visual Studio and attempted to interop with the service ......

WCF Client Endpoint Contract Changes Between VS2005 and VS2008
As I noted earlier, I recently converted a Visual Studio 2005 solution with WCF clients to Visual Studio 2008. After making some additional changes and running the application, I started getting errors instantiating the WCF clients. The message -- that the contract for my WCF client couldn't be found in the list of endpoints in my config -- was unexpected since I re-created my WCF clients with the same name (and in the same namespace) as before. After a quick inquiry with my colleague (and brilliant ......

Java Web Service Interop with a .NET Client
I recently had a requirement to interop with a web service (written in Java, not that it matters all that much what it was written in) with a quasi-unique set of security requirements. They were as follows: SOAP 1.1 Transport security was an option. Production endpoint was using SSL; test endpoint was not. Need the flexibility to turn this on or off. Message Security consisted of two tokens (both WS-Security 1.0) Unsigned username token with plaintext password (forget the argument about plain text ......

Biztalk Configuration Error: Cloned Machines
I recently ran into an error attempting to configure a Biztalk 2006 R2 instance on a virtual machine. I had a virtual services box (where Biztalk was installed) and another virtual SQL box (where the Biztalk configuration was kept). However, I kept getting an error during the configuration deployment step: Exception of type 'System.EnterpriseServices.... was thrown. After googling for a bit, I ran into an excellent article by Wade Wegner explaining that the two virtual machines ......

WCF Clients and the "Broken" IDisposable Implementation
I've been involved in a lengthy discussion recently at work involving the IDisposable implementation in WCF clients. The topic is a complex one, potentially involving discussion of fault propagation strategies, general IDisposable patterns, proxy lifetime patterns, and the like. However, for the purposes of this post, I'm only interested in the implementation details of IDisposable in WCF clients (specifically, System.ServiceModel.ClientB... Props to a very respected co-worker of mine, ......
