C# 5.0: await and Reentrancy
28 January 13 04:45 AM | pavely | with no comments

The relatively new async/await keywords in C# 5.0 are truly great. I’ve been using them for a while now, and I always contrast these to the way things can be done in C++11 ; and even with the help of PPL tasks – it stands out as clearly victorious, with its ease of use and lack of verbosity. In fact, it’s so easy to use that I find myself creating new methods that are mostly “Async”, even if the benefit may not be that great – just because it’s easy to do. For example, suppose there is a method that...

Making HTTP calls in WinRT with C++
14 January 13 04:36 AM | pavely | with no comments

When working with Windows Store applications (“metro”), it’s sometimes necessary to make HTTP calls. one classic example is to register for push notifications . After obtaining a unique channel URI, the app needs to send that URI to its application server, as that particular URI is the one to use by the application server to execute a push notification against the Windows Notification Service (WNS). Getting the channel URI is fairly simple, with a call to the static PushNotificationChannelManager...

Windows Phone 8: Integrating with the Wallet
08 November 12 11:18 AM | pavely | with no comments

Earlier this week, Microsoft held the Discovery event in Tel Aviv, Israel, with a distinguished guest, Steve Ballmer. In the event, Microsoft has officially launched Windows 8 and Windows Phone 8 (and XBOX 360 and Kinect…) in Israel. During the presentations, a wallet application on Windows Phone was shown, which was developed by us, CodeValue (and specifically by me ). This article and this one describe something about the app (in Hebrew). Here are some screenshots (some text is in Hebrew): In this...

Windows 8 Metro: C++/CX vs. C#
25 June 12 10:05 PM | pavely | 9 comment(s)

Lately, I’ve been doing development of a Windows 8 Metro application using C++ only (yes, that’s right, no C#) for a client. The reasons for that are mainly an existing C++ code base and a good C++ acquaintance that the team in question has. I’ve been using the new C++/CX extensions that make it easier to work with the Windows Runtime (WinRT); easier with respect to the Windows Runtime Library (WRL) that uses standard C++ with a bunch of helpers (such as ComPtr<T> as a smart pointer for a COM...

Visual Studio 2012 and C# 5.0: Upcoming session
02 June 12 03:47 PM | pavely | with no comments

I’m going to give a session at Microsoft offices in Ra’anana (Israel), on the 18th of this month, showing new features in Visual Studio 2012 (RC released a few days ago) and the new features of C# 5.0 (there are two. If you think about async/await – that’s one). The event is free, but you should register at https://msevents.microsoft.com/CUI/EventDetail.aspx?EventID=1032514296&Culture=he-IL See you there!

WPF 4.5 Cookbook
26 April 12 07:40 PM | pavely | with no comments

A few months back, I was approached by Packt publishing , asking me to write a WPF book, in their “cookbook” style, and I accepted. I haven’t written an entire book before, but I have written dozen of courses for Hi-Tech College, John Bryce Training and now for CodeValue , in a range of topics, from Windows Internals and device driver development, to advanced C++, to basic and advanced .NET topics, to WPF, and even some oddities such as the Windows Media Foundation . Writing a book, however, is different...

Asynchronous Programming with C# 5.0 & .NET 4.5 Session
26 March 12 01:38 PM | pavely | 1 comment(s)

This morning I gave a session on asynchronous programming with C# 5.0 at Microsoft offices in Ra’anana. Thank you all for attending, it was great fun! As promised, the presentation slides and demos are attached below (the Windows 8 demos can naturally be run on Windows 8 only). The session was recorded, so if you missed it, or just want to hear the same jokes again, the recording will be available in a few days – check out the MSDN blog for details of availability.

INotifyPropertyChanged implementation with C# 5.0
20 March 12 10:40 PM | pavely | 6 comment(s)

The INotifyPropertyChanged interface has become a very popular interface, typically used in MVVM scenarios (WPF/Silverlight). It looks simple, with a single member, which is an event, and its basic implementation by some data type may be something like this: class Book : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged( string propName) { var pc = PropertyChanged; if (pc != null ) pc( this , new PropertyChangedEventArgs (propName...

What happened to asynchrony with WebClient in .NET 4.5?
17 March 12 04:01 PM | pavely | 1 comment(s)

In the Visual Studio 2010 Async CTP , a bunch of extension methods have been added to the WebClient class, to facilitate the “awaiting” of C# 5.0, such as DownloadStringTaskAsync , which can be simply used like so: var wc = new WebClient (); string result = await wc.DownloadStringTaskAsync( "http://msdn.microsoft.com" ); One of the overloads present in the CTP accepts a CancellationToken , so that the operation could be cancelled by an external CancellationTokenSource . For example: async...

This month turned out to be a busy one for me, at least as far as public presentations are concerned. All sessions are free of charge, but you should register – details follow: Parallel and Asynchronous Programming with .NET 4/4.5 and C# 5.0 This session is to be held on the 20th, at John Bryce offices in Tel Aviv. I will do a quick recap of tasks and the Parallel class, and then move to async programming with and without the new C# 5.0 features. I will be using VS 2010 and the recently released...

Mandelbrot Set with C# 5.0 Async support
21 November 11 07:09 PM | pavely | 3 comment(s)

I’ve always been fascinated by the Mandelbrot set . It’s an intriguing set, and the fractals created are truly mind boggling. (for more information on the Mandelbrot, and other such sets, you can start with the above Wikipedia link). As part of my preparation for tomorrow’s session on C# 5.0 asynchronous programming, I’ve decided to create a WPF application to view and explore the Mandelbrot set, while taking advantage of those new asynchronous features. This turned out to be rather fun. Here’s the...
