Weathr is a fully functional 3D weather app that demonstrates the use of modern C++ (both ISO and C++/CX), DirectX, and XAML. It also shows the use of PPL and lambda expressions for asynchronous communication with REST-based servers.
Microsoft is now offering an official version of SQLite for Windows Phone, Windows Store, and .NET 4.5. The library is available as a Portable Class Library, so developers can use as a basis for their own portable libraries.
The recently released Nevron Open Vision enable development of cross platform presentation layer applications with support for Windows Forms, Windows Presentation Framework (WPF) and Silverlight. It will be soon updated to support Mac OS, iOS, Android and WinRT.
Telerik RadControls for Windows 8 XAML Q3 2013 includes RadRadialMenu and it helps you to create circular menus for both desktop and touch platforms. The control enables you to create both standalone and context menus.
During a UBS Global Technology Conference held last week, Microsoft’s Julie Larson-Green, EVP Devices and Studios, discussed her company’s approach to today’s software market, providing insights especially into the mobile device operating systems space. We selected the most interesting fragments from the session’s transcript (HTML, DOCX).
The recently released Windows 8.1 and Visual Studio 2013 Preview editions includes improved reporting for exceptions that enables C++ Windows Store App developers to easily identify and fix errors.
Private distribution of applications is possible for both WinRT and Windows Phone 8, but the experience is very different for the two platforms. Mobile devices cost 300 USD per year per company, while WinRT costs 3,000 for the first 100 computers or fraction thereof.
Windows 8.1 is set to make allow applications greater access to the People and Calendar data stores. The functionality will be exposed via contracts, the mechanism by which applications can send and consume messages from other applications and the operating system. All interactions will require user confirmation and applications will not be granted full access to the user’s contacts and appoints.
The recent release of Visual Studio 2013 preview edition ships with new diagnostics tools for measuring performance of Windows Store apps in addition to a new energy consumption tool. In his recent session at //Build, Pratap Lakshman analyzes the usage of these new tools supported by relevant demos.
The information in part 2 of Threading in the Windows Runtime deals with the internals of the threading model. This section, originally presented by Marytn Lovell at Build 2013, is intended to be trivia or possible useful in debugging, but not necessary for day to day development. For more practical information, please refer to part one of InfoQ’s key points summary.
During the Build 2013 conference Marytn Lovell revealed some of the inner workings of the WinRT threading model. While .NET developers may be surprised at its complexity, especially when multiple windows are involved, traditional COM developers are going to be relieved to learn that it is much simpler than what they are used to.
The three Pillars of Performance, Fast, Fluid, and Efficient, have been the common theme at the performance sessions this year. In the session XAML Performance Fundamentals we see ways to detect and solve problems that prevent us from achieving these pillars.
Testing is critical, but not enough. This is the theme of Harry Pierson’s session on application reliability in Windows Store apps.
A major emphasis of WinRT 8.1 is the ability to control devices over HID, Bluetooth, and USB interfaces. These devices range from toys and gadgets to Point of Sale (POS) hardware to powerful 3D printers.
Windows 8.1 brings with it a lot of much needed functionality to WinRT (i.e. Windows Store) apps that make is a viable platform for line of business and point of sale applications. These include multiple-window support, USB/Bluetooth integration, and a HTTP stack that is unified with Internet Explorer’s shared cache.
