What an interesting time to be a .NET developer!
In the last week, Microsoft held its now annual Build conference and announced a whole bunch of new product offerings and features. For most of us who can’t get there in person, downloading and watching the session videos is almost as good. All of the keynote and session videos are (or soon will be) available on the Channel 9 Build 2014 event page
Build doesn’t just focus on .NET – it tends to cover developer topics that relates to any Microsoft technology – Windows desktop, Phone, Web and Azure (cloud).
I remember having a conversation with Dan Shearer many years ago. Dan is a big advocate of open source software. I surprised him at the time by telling him about this XML-based installer software that Microsoft had made open source and hosted on SourceForge (10 years ago). I think this was still when other parts of Microsoft were still quite anti-open source. 10 years on, things have changed quite a lot.
We have not only the OuterCurve Foundation, but now just announced at the Build conference, the .NET Foundation to promote and ‘steward’ a collection of open-source technologies for .NET. Curious that they created a second foundation, but what ever gets the job done I guess.
The biggest thing in this area for me was the announcement that the new .NET C# and VB compilers (aka ‘Roslyn’) would become open source. They’re up now on CodePlex - http://roslyn.codeplex.com/ (and yes, they’re taking pull requests too)
My how things have changed!
Windows 8.1 Update 1 is out, and Windows Phone 8.1 is coming in the next few months. Apart from the new phone features, I think the big news here is the new “Universal” applications that make it simpler to develop a single app that works on both Windows Phone and Windows Store (aka Metro). Laurent Bugnion has more info on his blog. This is nice – though it only works for 8.1 so it doesn’t necessarily solve the problem of supporting older platforms (eg. Windows Phone 7 or the current Windows Phone 8 before the upgrade is released)
Watching the Day 2 keynote with Scott Guthrie impressed me with how much is going on in Azure land. I feel like I really need to get more familiar with this stuff.
- TypeScript 1.0 announced
- Cortana – like Siri but supposedly better
- .NET native compiler
- Seeing an iPhone and a Mac both used in demos – I don’t particular care about these devices but I know a lot of people do.
That will do for now – I’ve got some more videos to watch (if our monthly internet quota doesn’t get used up – I already managed to lose all my phone’s data quota when it decided to use 3G instead of the home wireless to stream the keynote )
I first became a Microsoft Certified Trainer back when I was working at LobsterPot Solutions. Teaching is something I quite enjoy, though the opportunities are limited. The only times I've been using my MCT status in the last few years was to be able to attend the Microsoft TechEd conferences as a hands-on labs trainer.
Recently, Microsoft announced some changes to the MCT programme, including that MCTs must teach at least one course a year, and that receive a training quality score (feedback) of at least 6.
As it's been a few years since I last taught a course, I won't be able to renew my MCT this year. They have introduced an 'MCT Alumi' programme for inactive trainers, which I would qualify for, but I haven't decided if there's value in me doing that.
I've been looking at ways to extend and enhance .NET WinForms controls recently and thought I'd summarise what I've found/learned so far.
The most obvious way to extend a control is to create a new class that inherits from the existing class. You then have full access to add new properties and methods and access any protected methods from the base class.
It does mean that if you've already used the control in your application, you're going to have to replace references to the base class with your new class – not always easy.
Another option is to create a class that implements the IExtenderProvider interface. You can then create a component that can be added to a form or user control that extends specific types. An example of this that ships in the framework is the ToolTip class. When you drag this control onto a form it doesn't add a visible control to the design surface. Instead it adds a new ToolTip property to appropriate controls on the same form.
A more specific area of WinForms controls that you might want to customise is the localisation support. Localisation for controls on a form is enabled by setting the Localizable property of the form to true. This also alters the designer-generated InitializeComponent method to add a new resources variable of type System.ComponentModel.ComponentResourceManager. This allows you to use .resx resource files to load locale-specific values for properties. This is the standard way that you would provide alternate language translations for your application.
A question on Stack Overflow asked about replacing this implementation with another that could load resources from an alternate location (such as an XML file or a database). The accepted answer pointed to some samples from Guy Smith-Ferrier's book, .NET Internationalization: The Developer's Guide to Building Global Windows and Web Applications.
Impressively, even though the book was published in 2006 Guy has been releasing regular updates to the code samples at http://www.dotneti18n.com/Downloads.aspx. His sample for a custom ComponentResourceManager includes a ResourceManagerSetter class that has the DesignerSeralizer attribute. This was new to me, but it turns out this is the mechanism that generates the code that appears in a forms's .Designer.cs file. This uses the CodeDom to generate code that inserts the replacement ComponentResourceManager instance.
private void InitializeComponent()
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(UserControl1));
this.resourceManagerSetter1 = new Internationalization.Resources.ResourceManagerSetter();
this.label1 = new System.Windows.Forms.Label();
Internationalization.Resources.ResourceManagerProvider.GetResourceManager(typeof(UserControl1), out resources);
this.label1.Name = "label1";
Using CodeDom means that the code is generated for the appropriate language automatically. The only requirement is that this component must be the first one added to the form. If you're adding this to an existing form with controls, just go to the Designer.cs file and move the line calls the constructor to the top of the InitializeComponent method. (The order of the calls to the constructors seems to determine the order in which the serialized code generators are called)
You can see from the code sample above that the original instantiation is still there, but is effectively replaced by the call to the GetResmourceManager method.

We made it!
I'm glad to report that unlike last year, my back was behaving itself and yesterday I was able to take part in the Bupa Challenge Tour with my Dad. The Challenge Tour is a chance to ride the same route that the professionals do for one day of the Tour Down Under. Like previous years, we rode as part of the Mud, Sweat & Gears team.
We rode the full course of 154km from Unley to Victor Harbor. That's the longest distance I think I've ever ridden, and boy did my feet and my behind know about it – especially the last 30km or so! It took just under 8 hours (7:54 according to the Endomondo app I used on my phone), which included time at the rest stops.
The start of the ride took us up the South-Eastern Freeway through the Heysen Tunnels. Normally cyclists aren't allowed along here, so that was quite a novelty – though we agreed that the tunnels themselves are quite stuffy.
The weather this year was fantastic. It was a little drizzley early in the morning, but then remained comfortably cool for most of the day. It was overcast for most of the morning, which helped a lot. A gentle breeze earlier in the day became a little more blustery towards the end, but not as bad as some years.
We made three stops along the way – at Meadows, Mt Compass and Yankalilla. A chance to refill drink bottles with various colours of Powerade (each stop seemed to have a different colour) and grab a banana and fruit cake to refuel.
This year for the first time they scanned the RFID tags on our bikes as we progressed through the route. You could then log in to a website to obtain the results. Here are mine:
|Split ||TOD ||Time |
|Unley ||06:42 am ||00:12:16 |
|Unley Backup ||07:09 am ||00:39:30 |
|Stirling ||07:53 am ||01:23:13 |
|Meadows ||09:03 am ||02:33:57 |
|Mt Compass ||10:30 am ||04:00:13 |
|KOM ||11:48 am ||05:18:17 |
|Yankalilla ||01:13 pm ||06:43:55 |
|Finish ||02:37 pm ||08:07:25 |
The ride started at 6.30am, but you as can see it took us 12 minutes to pass through the start – not surprising as there were thousands of riders there.
- Repeatedly being overtaken by former UniSA colleague Mandy (apparently I'm quite conspicuous on a bike, even amongst 6,600 other similarly attired cyclists)
- Well run food and drink stops
- Watching the pros finish in a blaze of colour
- They'd temporarily closed the lunch station as the pros were approaching the finish line and there just a few salad roles in a tray. I gather earlier finishers had a better selection. We didn't starve, but it didn't seem to be very organised.
- I wonder if there's such thing as a saddle that's comfortable even after 100kms. I don't think I have one
- Lemons as a choice of fruit at the food stops. Didn't seem to be a lot of takers.

Special thanks to Narelle's parents Rick and Margaret, who drove us to the start very early in the morning, and then met us at the finish to take me and our bikes home again.
"Sad, funny, thoughtful, thankful"
I wrote that on Facebook this afternoon after having returned from Eudunda where I had the honour and privilege of farewelling the father of a dear friend.
Max was a much loved husband, father and grand-father. It was great to see so many people come together today at his funeral to pay their respects and celebrate his life.
I did not know Max that well, but to hear the story of his life today, and see his legacy in his four daughters and their families was both moving and inspiring.
A man of faith and integrity.
It gives you pause to consider that when it's your turn:
- what will people say about you?
- will people still know how to make the jelly cakes, slices, curried-egg sandwiches, party pies and other assorted delights you find at the afternoon tea?
