Silverlight and Windows Phone usergroups

30 Sep

Over the summer we have started two new usergroups in Denmark: A Silverlight usergroup (SLDEV) and a Windows Phone usergroup (WPDEV). Both usergroups have some key members that are very passionate about the technologies. By the time of writing each usergroup got more than 100 members – that is really cool!

Next week we have our first official event in the Silverlight usergroup. TV 2 Denmark (large Danish broadcasting company) talks about why they have chosen Silverlight and we take a technical walkthrough of their Silverlight based video player.

Later on next week Nikhil Kothari visits Copenhagen (YEAH!!!). The Silverlight usergroup have arranged a 2 hour talk by Nikhil about WCF RIA Services.

In the Windows Phone usergroup we have planned to do a code camp tour around Denmark during October. You can see the events at Eventbrite:

Getting ready for JAOO

28 Sep

On Sunday I’m doing a full day training session about Silverlight, Windows Phone 7 and Azure. All three technologies are huge and great at their own but together they give a truly amazing development platform.

Doing the session the participants will learn to develop a Silverlight webshop running in the browser and they will learn to build an out-of-browser Silverlight application to administrate the webshop. To take it one step further the participants will learn to develop a simple shop for Windows Phone 7 (yes, I will bring a developer device!). Finally the participants will learn to host the applications in Windows Azure and to store the data in SQL Azure.

ResourceDictionary in WP7

27 Sep

WP7 is based on Silverlight 3+ and by default it’s not possible to create a new resource dictionary. However it’s pretty easy to work around – just follow the same guidelines as if it was in Silverlight 3.

1) Create a new Class and rename it YourResourceDictionary.xaml (or whatever fits you).

2) Replace the content from the Class with the content you need:

xmlns:x=”” >
<!– Your resources goes here –>

3) Unless you’re creating a Generic.xaml resource dictionary in the Themes folder you need to add the resource dictionary to the list of merged resource dictionaries in your App.xaml file:

<ResourceDictionary Source=”YourResourceDictionary.xaml” />

Your resource dictionary will now be loaded as part of the application resources to your WP7 application.

Frame and Page Navigation Overview for Windows Phone

23 Sep

Most Silverlight browser and out-of-browser applications can benefit from using Frames and Navigation. Silverlight applications on Windows Phone almost need Frames and Navigation. This little article gives a good overview of the terms and explain how and where to use the different parts.

Silverlight 4 minimum requirements

22 Sep

If you’re looking for the minimum requirements for Silverlight 4, you will probably browse to or to However if you go to you will get disappointed – the minimum requirements listed is for Silverlight 3.

Windows: Intel® Pentium® III 450MHz or faster processor (or equivalent)
Mac OS: Intel Core™ Duo 1.83GHz or faster processor

I was told by Microsoft that the minimum requirements remains the same for Silverlight 3 and Silverlight 4. However if you go to the Silverlight install page you can see the minimum requirements for the most current version of Silverlight (4.0.50826.0):

Windows: X86 or x64 1.6-gigahertz (GHz) or higher processor
Macintosh: Intel Core Duo 1.83-gigahertz (GHz) or higher processor

I’m confused… Well, for future requests regarding the minimum requirements I would choose the Silverlight install page.

Edit: Turned out that the information on the FAQ was wrong and will be corrected. Minimum requirements is 1.6 GHz.

During the past 3 weeks I have been planning a code camp tour with the rest of the Windows Phone user group in Denmark. In four weekends in a row in October we are going to visit Aarhus, Aalborg, Odense and Copenhagen. The code camp will offer lots of training, hands-on experience and of course an opportunity to play with some phone 7 devices :)

Silverlight and SharePoint 2010

14 Sep

I have done quite a few courses, workshops and presentations about Silverlight. Last week I did a 4-days Silverlight 4 course and I’m doing a 3-days Silverlight 4 line-of-business course in November (

Silverlight is becoming more and more widely used and with the latest release of SharePoint we get a much easier way of using Silverlight to generate WebParts. No doubt that we will see a lot of Silverlight inside SharePoint in the future.

I thought about doing a 1-day hands-on workshop about how to do Silverlight for SharePoint. Anybody interested?

Valuable lesson learned about Azure

13 Sep

For the last two months I have been working on a Silverlight project hosted on an Azure platform. I have had my challenges with Azure but all things considered I think it is a really good platform. It’s without doubt that I can say my next Silverlight application will be based on the Azure platform as well.

But – there’s one thing that hit me pretty hard. The bill. For the last month I got a bill for 3300 computing hours!!!Windows azure got both a Production and a Staging environment and apparently (and fair enough) I pay for every hour for both environments and for every site I have active. Since then I have suspended all of my Staging environments when not needed.
