Microsoft did a fantastic job making PDC09 accessible to everyone, even to geeks as far away as Vermont. Their real-time HD video coverage of the keynotes and conference presentations was awesome. And what Microsoft didn't provide at http://microsoftpdc.com, Twitter did. The combination of microsoftpdc.com and the #PDC09 stream allowed me to feel like I was at the conference without having to fly across the country to get there. Fascinating, really, the ability to follow the flow of a PDC conference in real time, being in on the pre-conference anticipation of the attendees, initial disappointments as the conference got off to a slow start, the bitching about snacks, reading about the parties, seeing reactions to the free laptops on day two...

I am yet to find a proper sample on how to do realistic Test Driven Development (TDD) and how to write proper unit tests for complex business applications, that gives you enough confidence to stop doing manual tests anymore. Generally the samples show you how to test a Stack or a LinkedList, which is far simpler than testing a typical N-tier application, especially if you are using Entity Framework or Linq to SQL or some ORM in data access layer, and doing logging, validation, caching, error handling at middle tier. There are many articles , blog posts , video tutorials on how to write unit tests, which I believe are all very good starting points. But all these examples show you basic tests, not good enough to let your QA team go. So, let me...

When I finalized my article about memory leaks , I removed a part about Infragistics NetAdvantage. Here it is. It may be useful to some of you. Warning: It's based on NetAdvantage 7.3, and may or may not apply to recent versions. Let's take an example. In project X, visual controls from the Infragistics NetAdvantage suite are used to build the GUI. One of these controls is the UltraToolbar. As told by its name, this control is used to display toolbars. The way a UltraToolbar is used is via a UltraToolbarsManager component. This works fine, except that even though the UltraToolbar class implements IDisposable, the UltraToolbarsManager class never calls the Dispose method on the UltraToolbars it manages. This is a bug. Fortunately, a workaround...

Microsoft Canada’s Adam Gallant gave an excellent presentation today on ‘What’s New with Visual Studio Team System and MSDN’. Among Adam’s demonstrations were the new APIs to support so-called manycore architectures. Most of us are still writing code as if we only have one processor when it fact newer machines are likely to have four of them. The .NET Parallel Extensions supported in VS 2010 lead us into adopting these new technologies, which is fine. However, some of us at the session were wondering...( read more ) Read More...

Just a decade and a half ago, the process of building a simple Windows-based application could have been described as a nightmare. The introduction of Visual Basic changed it so developers could for the first time implement Windows applications in an intuitive, graphical environment by dragging controls onto a form. The web revolution is here and now. Web had become very quickly the platform of choice for all kind of applications. The demand for web applications is ever growing and cloud computing...( read more ) Read More...

So the Silverlight platform has been quite interesting for some time in concept, and had some niche abilities that made it perfect for streaming media, or writing simple rich applications. Around the time of Silverlight 3 things started to get interesting; as the tools developed, and the platform matured! Enter, Silverlight 4! For those of you that have been waiting to adopt this technology into your own development lifecycle, I truly believe your wait is over. Difficult or downright impossible things inside Silverlight applications have now been overcome. Limitations such as Printing, Local File Access, mouse scroll wheel support, and out of browser experiences. There has been a huge stir of Silverlight 4 activity at PDC09 this year (where...

After I graduated from the HIO Enschede (B.Sc level) in '94 I have worked with a lot of different platforms and environments: from 4GL's like System Builder, uniVerse and Magic to C++ on AIX to Java to Perl on Linux to C# on .NET. All these platforms and environments had one thing in common: their creators were convinced their platform was the best and greatest and easiest to write software with. To some extend, each and every one of them were decent platforms and it was perfectly possible to write software with them though I'll leave the classification whether they were / are the greatest and easiest to the reader. I'll try to make clear below why this dull intro is important. Yesterday I watched the live stream of the PDC '09...

Several of the customers I work with are looking to build kiosk or point-of-sale applications with Silverlight . The ease of deployment with browser-based Silverlight applications is definitely appealing. Sharing applications or components between customers’ kiosks and web sites is another appealing reasons to go with Silverlight. This post outlines the architecture decisions between Silverlight and WPF and presents architecture options for Silverlight based solutions. A follow up post will discuss the Silverlight implementation details. However, POS systems or kiosks often need integration with local peripherals, such as credit card readers, barcode scanners, printers, etc. Since Silverlight browser applications run in a sandbox access to these...
