Past, present and future of

C# and .NET

Kathleen Dollard

Director of Engineering, ROICode [email protected]

Coding: 2 Advanced: 2

“In the beginning there was…” Take a look back at over 15 years of .NET and C#

evolution and look into the future driven by enormous underlying changes. Those changes are driven by a shift in perception of how .NET fits into the Microsoft

ecosystem.You’ll leave understanding how to leverage the .NET Full Framework,

.NET Core 1.0, .NET Standard at the right time. Changes in .NET paralleled changes in

the languages we’ll reflect on how far C# and Visual Basic have come and how they’ve

weathered major changes in how we think about code. Looking to the future, you’ll

see both the impact of functional approaches and areas where C# probably won’t go.

The story would not be complete without cruising through adjacent libraries – the

venerable ASP.NET and rock-star Entity Framework that’s recovered so well from its

troubled childhood.You’ll leave this talk with a better understanding of the tool

you’re using today, and how it’s changing to keep you relevant in a constantly

morphing world.

    T-Mobile and Metropcs Continue to Expand Consumer Choice, Will Offer New Windows Phone 8.1 on Nokia’S Upcoming Lumia 635

    T-Mobile and MetroPCS Continue to Expand Consumer Choice, Will Offer New Windows Phone 8.1 on Nokia’s Upcoming Lumia 635 BELLEVUE, Wash. – April 2, 2014 – Immediately on the heels of Microsoft’s Windows Phone 8.1 unveiling today, T-Mobile US, Inc. (NYSE: TMUS) has announced the company will offer up its Redmond neighbor’s latest mobile OS as part of its ongoing commitment to deliver greater freedom and choice for American wireless consumers – starting with Nokia’s new Lumia 635 coming this summer. The Lumia 635 will be the first device sold in the United States powered out of the box by the very latest Windows Phone 8.1 operating system, introduced earlier today at Microsoft’s 2014 Build developers conference in San Francisco. T-Mobile US today also announced that, come summer, T-Mobile and MetroPCS will be the best places to get the very first smartphone with the new Windows Phone OS for a low upfront cost and with zero service contract, zero overages (while on its wicked-fast network), zero hidden device costs, and zero upgrade wait. And only T-Mobile and MetroPCS customers can experience the next-gen Lumia 635 on America’s fastest nationwide 4G LTE network. “The Un-carrier’s all about removing crazy restrictions and delivering total wireless freedom and flexibility,” said Jason Young, senior vice president of Marketing at T-Mobile. “With Windows Phone, we can offer customers another great choice in mobile platforms. And we’re excited to bring to both T- Mobile and MetroPCS customers the combination of next-gen software, great features and fresh design that Nokia’s latest Windows Phone has to offer.” The Lumia 635 will build on all the qualities and benefits that made its predecessor – the Lumia 521 – so popular among American wireless customers.

  • Taking the Metro with Windows Phone

    Taking the Metro with Windows Phone

    1 Taking the Metro with Windows Phone WHAT ’ S IN THIS CHAPTER ➤ How Windows Phone has changed Microsoft ’ s approach to the mobile industry ➤ What the Metro Design Language is and how it came about ➤ An overview of the Start and Lock Screens and how they help users access information on the phone ➤ Why the use of Hubs creates a more connected user experience ➤ What it means to be a Windows Phone developer Microsoft has been building mobile devices for well over 10 years, starting with a variety of Windows CE- based devices, such as the Handheld PC and the Palm- size PC, fi rst released in 1996. Beginning around 2000, these disparate operating systems began converging into what became Windows Mobile, based on the principle of delivering a PC to your pocket. New features were predominately driven by enterprise needs such as device management and security. This eventuallyCOPYRIGHTED worked to the detriment ofMATERIAL the platform as it didn’ t appeal to the average consumer. Devices were more robust than sexy, and the user interface mirrored that of the desktop, even having a Start menu, rather than providing an experience. Throughout this chapter, and in other parts of this book, there will be references to both Windows Mobile and Windows Phone . This is intentional, and they are not the same thing. Windows Mobile refers to the previous mobile operating system from Microsoft that at the time of writing is Windows Mobile 6.5.3. Windows Phone refers to Microsoft ’ s latest offering in the mobile space and starts with Windows Phone 7.

  • Introduction to Windows 8

    Introduction to Windows 8

    [Not for Circulation] Introduction to Windows 8 Windows 8 is a completely redesigned operating system developed from the ground up with touchscreen use in mind as well as near instant-on capabilities that enable a Windows 8 PC to load and start up in a matter of seconds rather than in minutes. Windows 8 Vocabulary Apps - "App" is another word for program. In Windows 8 , some apps come built-in to Windows, and there are even more available in the Windows Store. Live Tiles – Interactive apps that take advantage of Internet access to provide real-time updates. Hot Corners - The corners on your screen are hot corners and give you access to different Windows features. Charms Bar - Contains a set of buttons and commands that control the application you are currently using, as well as provide options for system settings. The Charms bar includes many of the features previously available from the Start button. Metro-style - New layout of Windows 8 with tiles and apps instead of the standard desktop with a Start button. Mobile - Windows 8 is designed for mobile devices, such as tablets. You can also sign into your Windows 8 screen anywhere using your Live ID, and your customized settings travel with you. Touch-centric – Touch is a key element in Windows 8; however, a traditional mouse and keyboard can be used as well. Speed Bump - The small gap between groups of tiles. Speed bumps can be added to create new groups. Where Do I Find: Shut down - Move your mouse to the upper right corner of the screen, and move your mouse down until you see your charms appear.

    US-China Strategic Competition in South and East China Seas

    U.S.-China Strategic Competition in South and East China Seas: Background and Issues for Congress Updated September 8, 2021 Congressional Research Service https://crsreports.congress.gov R42784 U.S.-China Strategic Competition in South and East China Seas Summary Over the past several years, the South China Sea (SCS) has emerged as an arena of U.S.-China strategic competition. China’s actions in the SCS—including extensive island-building and base- construction activities at sites that it occupies in the Spratly Islands, as well as actions by its maritime forces to assert China’s claims against competing claims by regional neighbors such as the Philippines and Vietnam—have heightened concerns among U.S. observers that China is gaining effective control of the SCS, an area of strategic, political, and economic importance to the United States and its allies and partners. Actions by China’s maritime forces at the Japan- administered Senkaku Islands in the East China Sea (ECS) are another concern for U.S. observers. Chinese domination of China’s near-seas region—meaning the SCS and ECS, along with the Yellow Sea—could substantially affect U.S. strategic, political, and economic interests in the Indo-Pacific region and elsewhere. Potential general U.S. goals for U.S.-China strategic competition in the SCS and ECS include but are not necessarily limited to the following: fulfilling U.S. security commitments in the Western Pacific, including treaty commitments to Japan and the Philippines; maintaining and enhancing the U.S.-led security architecture in the Western Pacific, including U.S.

Starting with an app built with the basics of the Xamarin.Forms toolkit, well go step by step through several advanced topics to create a solution architecture rich with the benefits of good design patterns and best practices.Well start by introducing a core separation between the apps user interface and the apps business logic by applying the MVVM pattern and data-binding. Then we will focus on building out a layer of plugin-like services that handle platform-specific utilities such as navigation and geo-location, as well as how to loosely use these services in the app with inversion of control and dependency injection. Next well connect the app to a live web-based API and set up offline synchronization.
