Last week, I was busy with another user group tour in the UK for Telerik. This year, I was able to give a total of 7 sessions in 4 cities (Hereford, Cheltenham, Bristol and Southampton). A lot of people stopped by to join me on an exploration of some Windows 8 and Windows Phone talks. During the talks, we looked at the upcoming Telerik controls for Windows 8 which will make LOB development much easier in the Windows 8 space!

Here are some of the pictures of some of the evenings:

Gill Cleeren     Events | Speaking | telerik     December 4, 2011    

To complete the travelling of 2011, I spent the last week of November touring the entire UK for another user group tour for Telerik (the second one in the UK this year). Telerik is very active in the support of user groups: through the Telerik Insider program, speakers can be requested to go and talk to user groups all over the world, entirely sponsored by Telerik. During the talks, which are deep-dive technical talks, licenses and swag is given to attendees.

This tour brought me in the Northern part of the country, more specifically, I visited a user group in Liverpool, Newcastle, Edinburgh and Aberdeen. At each location, we did 2 sessions. One of these that we “repeated” at each location was an introduction to Windows 8 and WinRT development. This of course triggered a lot of interesting discussion and questions. Each stop also filled their rooms quite well! We were lucky to have good weather (we had, apart from one single rain shower, not a single day of rain in Scotland in the last week of November!) so I made all the cities in place. Also, the weather triggered high show-rates.

I brought home a few things from Scotland, including a cold that is now in its 10th day. This caused me to be delayed in posting all the content. But now, without further delay, here’s all the files (slides and demos) of all talks:

Windows 8 – Windows Runtime: slidesdemos

Liverpool: Building a Windows Phone 7 app from start to finish:

Newcastle: Silverlight and Azure

Edinburgh: Building a Windows Phone 7 app from start to finish

Aberdeen: Silverlight 5 for LOB Development

I hope you enjoyed it. Thanks for all the user groups for their work!

I’ll be at Ordina Netherlands (Nieuwegein) for the ”Innoveer jij mee” event on February 7th.
SilverLight 4 door Gill Cleeren
Op maandag 7 februari a.s. geeft Gill Cleeren een masterclass. Gedurende het programma is er aandacht voor de positionering van Silverlight met name in het licht van desktops en mobile devices (als Windows Phone 7). Natuurlijk is er aansluitend veel aandacht voor de technische in’s and out’s van Silverlight 4 en de wijze waarop applicaties met Silverlight 4 ontwikkeld kunnen worden.

Silverlight is Microsoft’s platform voor het ontwikkelen van Rich Internet Applications (RIA’s) op desktops en mobile devices als Windows Phone 7, Microsoft’s nieuwe mobiele platform.

Microsoft heeft veel geïnvesteerd in Silverlight en Silverlight is inmiddels toe aan zijn vierde iteratie (Silverlight 4) en daarmee klaar voor de ontwikkeling van business applicaties.

Yesterday, I arrived back home after touring Sweden for a week. I gave presentations in Malmö, Stockholm, Örebro and Götherborg. Each session was attended by a great number of developers, all members of Swenug. The sessions were sponsored by the people at Telerik: at each session, I got to give away some cool prices from Telerik, including in each city a Telerik Ultimate Collection!

Gill Cleeren     .NET 4 | .NET Show | Efficiency | Speaking | Windows Azure     September 26, 2010    


Dear readers, I’m excited to announce the launch of .NET Show, the Belgian podcast for .NET developers. I’ve been working on this project for some time now and today, we are launching the site AND the first episode!

What is .NET Show?

Together with Katrien De Graeve, I’ll be recording podcasts on .NET development (in the broad sense of the word, so everything related to .NET) from now on. Our goal is bringing you in contact with all corners of the Microsoft development stack, from Silverlight to Azure, from COM interop to ALM... In our podcasts, we are focusing (initially at least) on local guests and we will be doing most shows in Dutch. This way, we can differentiate ourselves from the numerous podcasts already available. The topics, while on .NET of course, can be something that the guests has been working on (a professional project, a hobby project), a technology you have been investigating, something you think that can be interesting for others to hear about etc.

The first first episode can be downloaded already. In this first episode, we are talking with Maarten Balliauw on Windows Azure and the Microsoft cloud strategy in general.
In episode 2, which we’ll put online in the coming week, I’m talking with Pieter Gheysens on ALM (Application Lifecycle Management) in Visual Studio 2010. And in episode 3, I’m sitting down with my co-author Kevin Dockx and we will be discussing WCF RIA Services in real-life projects.

If you are interested in doing a podcast, let me know! Send me a mail at and I’ll contact you. If you have any remarks or questions, send them to that address as well!

So, with that, I hope you’ll enjoy our podcasts! Head over to where you can find the first episode. If you want (and I know you will) to subscribe via iTunes or another podcast downloader, use this link: podcastIconTo add .NET Show to iTunes, go to Advanced – Subscribe to Podcast:

In the window that appears, enter the following URL:


.NET Show will now appear in your subscribed podcasts!

Gill Cleeren     .NET 4 | Efficiency | Personal | Silverlight | Speaking | TechEd     July 13, 2010    

Microsoft just announced that all of us can help deciding which sessions will be delivered at Tech-Ed 2010 Berlin. That's a great way of making sure that the contents is what the public wants!

I've ran through the list and 4 of my proposals made the shortlist (which is good news :)).

  • Treasures for the C# developer in Visual Studio 2010
  • AJAX Tips and tricks: things you never knew that could be done in ASP.NET Ajax
  • Silverlight data access and services not for the faint of heart
  • The good, the bad and… well, that’s it: Comparing good and bad practices in Silverlight application development

If you would like me to deliver one of these sessions on the upcoming Tech-Ed, please vote for them at . Of course, there are many really other interesting sessions there as well: I'm sure this will be a great conference!

Thanks for voting!
