SDN Cast 64 – Live at 8 with C# 8 and Android 8


Lucky 8, this week is themed number 8 … We are broadcasting the Dutch SDN Cast 8 squared = 64, Mads Torgersen was interviewed by Seth Juarez on C# 8 discussing features like Nullable Reference Types, Async Streams, Default Interface Implementations and Extension Everything. C# 8 is still in the planning phase but as with previous releases Mads shares the things the C# team are thinking about to put in the next release. Features obviously may be dropped or can be changed for the final release but the recording shares a lot of new stuff with the public already.

Also, Android 8 aka Android Oreo was released this week. Another 8 for us to consume. The Dutch Android site is still on Android Nougat but setting the locale to United States changes the site to Oreo.

Another big thing this week is Gamescom, where Microsoft opened the pre-order for Xbox X aka Xbox Project Scorpio. With this Xbox is opened for any games developer. Xbox used to be closed for development unless you were one of the certified game developers. This restriction is now lifted and only thing you need is a Dev Center account that you can purchase for $20 one-time fee.

Another demo this week, this time Skype integration on your website with two lines of code. How to easily put Skype interaction on your site, to living persons or even bots.

As usual we are always looking for presenters for our own events and Meetup’s so if you want to share something about hot technologies or just about something you implemented at work or in an App that could be interesting to our audience let us know so we can schedule you for one or our next SDN events or Dutch .NET Group Meetups.

This off course also goes for if you want to write a great article for us to publish in our SDN Magazines or at our SDN Website. The downside of publishing a magazine article is that there can be sometime between writing the article and publishing the magazine. So, if it is time critical sometimes the best option is to publish it on the website to get more speedy attention to the article.

As you see, options enough to address your audience with top notch information. You can even, if you like, be our guest in our SDN Cast shows to discuss the projects you are working on or other topics you master. We will instruct you how to connect with us and what it is you need to join the show.

Hopefully we will see you at our weekly web cast, for the schedule go to for next week’s announcement to find out the day and time of our next broadcast or go to to watch old episodes and videos that we recorded at our events. Don’t forget to subscribe our YouTube channel or go directly to YouTube not to miss any of our shows!

Xbox at gamescom 2017 Live


Anybody who knows me, knows that besides Technology and Programming I’m very much into Gaming, Music and Movies. Not that I have much time for gaming, it still is one of my ‘big’ things. The technologies used in games often arrive years later in ‘real world’ scenarios. I always wanted to be a games developer (don’t we all?) but ended up to develop Office applications Disappointed smile … Almost the same isn’t it?

I do make (a lot) of time for movies, I have an ‘all you can eat’ subscription for the local cinema and forces me to walk over there instead of driving to keep me a bit healthy. In a way the movie is the ‘reward’ for the walking effort.

Anyway, back to gaming. I’m looking forward to hear and see what is going on with Xbox X (Project Scorpio) and expect to get more information today from gamescom.

Today at 9:00 PM CST, 12:00 PM PDT Xbox @ Gamescom will be broadcasted live from the venue in Germany showing off the news and games for 2017-2018.

You can watch the streams live at:

  • Stream with English Closed Caption:
  • Stream with English Open Captions (burned in video):
  • Stream with German Open Captions (burned in video):

  • Also follow the newsfeed on Twitter by keeping an eye on hashtag #XboxGC

    Have fun!

    Week 9 – SDN Cast News, looking for the answer with André Obelink

    SDNCast 42

    With the twentieth anniversary of Visual Studio and the forty-second broadcast of our Dutch SDN Cast we speak with André Obelink on the subject of VB (Visual Basic) and the future of it. Forty-two is also the answer to life, the universe and all according to the Hitchhikers Guide to the Galaxy. Enough reasons to check out the recording on YouTube for this week.

    André Obelink is Microsoft MVP and author of six books, five covering Visual Basic and the sixth written with co-author Sander Gerz on C#.

    You can find André Obelink at several places such as
    Twitter: @obelink

    A returning question by many developers is will Visual Basic be around in the near future and if so where will it be positioned by Microsoft. A valid question, as it often appears that also with Microsoft Visual Basic seems to be the ‘forgotten’ language. APIs, sample code and documentation is released for C# at first and following a bit later the VB submission (sometimes we are still waiting for VB equivalents to arrive). We discuss all of this in depth, so if you are Dutch speaking look at this week’s Dutch SDN Cast.

    Next to Visual Basic several other subjects get by, from the light-hearted topics such as Xbox Gaming to the very extensive exercise to write books and again – is there a future in book writing.

    All in all enough topics making it well worth to jump to YouTube and watch the recording of the 42nd Dutch SDN Cast if you haven’t already watched it live last week.

    Where can you find SDN Cast 42?
