VSTO not supporting side-by-side Office installations
It took be a while before I realise that while Office 2003 and Office 2007 can be installed side by side, and that it doesn't really matter which version is installed first, it is an entirely different story when it comes to developing Office solutions using VSTO on a development environment with both version installed. In a nutshell, it is not supported and highly unrecommended to have both versions installed when developing using VSTO. The main reason is due to the 2007 Primary Interop Assemblies ......

Machine.Config, Web.Config and Configuration Inheritance
I was trying to set up a development server recently on a 64 bit machine with Windows Sharepoint Services 3.0 and came across this. After installing the server farm, while Sharepoint tries to load the Central Administration page, it popped up with this error This can be easily fixed by going to your parent web.config file under C:\Windows\Microsoft.NET\Fr... and change to allowOverride="true", this allows the Sharepoint's webconfig to override the settings in your parent configuration ......

How do you invoke a Workflow from WCF Service?
It took me a while to come to this blog post from Bart. He wrote a very simple and easy to understand article on how you can invoke a workflow engine from a IIS / Self Hosted WCF service. This is very useful from the layered architecture perspective since most service-oriented systems will not have the presentation layer calling the workflow engine directly. More often than not (depending on the complexity of the system), you will want to inject a communication service layer in the middle to handle ......

Quick guide in accessing WCF Service via Web Application
I was writing a proof of concept which uses WCF, WF and ASP.Net 2.0 and across some problems when I tried to call a WCF service from the web application client. Turned out that I spent an hour wasted trying to debug my application because I did not place the proxy.cs file into the App_Code of the web application. I had it documented down and wrote a simple and straight forward tutorial on how you can use a web application to access and call a WCF Service. The article is uploaded into the article ......

Web 2.0 is about linking people
I don't normally blog about this things or embed videos in blogs, as I think its quite annoying. This video, however, made me want to post it up. I stumble upon it in YouTube and thought it was pretty cool and perfectly logical. Take a look at it, and you'll probably agree ......

WPF not good for corporate applications?
A recent chat with Microsoft strengthened my perception that WPF is just not cut out for rich client applications front end. We know that WPF is an extremely powerful front end technology that can fulfill the development of a rich client application. Not only can it be used to design a rich client application, it can even be hosted on the Internet browser as a "web application". However, it is really not made out to for that kind of use. What WPF is good for, is media rich applications. If you need ......

That annoying "Could not find endpoint element with name..." error
While developing WCF client/services, I frequently encounter this annoying error whenever I run my client to connect to the service contract for the first time. I term them as "timewasters". This post will partly serve as a reminder to me, and hopefully someone will benefit from it if they came across the same problem. The story goes like this, you start up your usual Visual Studio 2005 to work on a simple WCF's application (you know the usual service <-> client stuffs). So you created your ......

Strange IIS "Failed to start monitoring directory changes" error
IIS 6 recently popped out an error when I am unable to replicate. I think this will be worth noting here for the sake of those who had the same encounter or who doesn't want to spend too much time debugging a "it should work" problem. This problem and it's resolution is documented in MSDN here. However, for some reason, the recommended methods did not solve my encounter. Here are the steps to first created this problem, note that subsequently the same steps will no longer reproduce this error. Create ......

Some differences between Indigo and WCF
There're some difference between Indigo and WCF which I'll highlight here. 1. WsProfileBinding is not longer therewsProfileBinding is a secure, reliable and interoperable binding based on WS-Reliable Messsaging and used for one-way service contracts. Basically it's fire and forget. The current downloadable WCF installation no longer uses wsProfileBinding, instead you should use wsHttpBinding to replace that and use Reliable Session to configure that in the config file to enable reliable messanging ......
