WP8 Development 17-23

Overview and persisting

Having built the SoundBoard app with lesson 1 through 23, I have been writing code, along with each video, while adequately commenting. I now have an unambiguous overview of Windows Phone 8 development and to challenge myself, I have volunteered for the opportunity to build the Windows Phone 8 interpretation of an app that is already available for iOS and Android, of which the SoundBoard app will be a great resource. I am going to repeat lesson 1 through 23, but not through video, rather, the text and screenshot version of each lesson and my source code commenting. It won’t be the app that I’ll build and of which I will publish the source code of (as communicated in C#: Day 2), but I will write a blog post of the trial and tribulation, methodology and result of my first attempt at an app. Most of what the app will be is accounted for with the SoundBoard app, but not everything, including the part that Bob Tabor challenges you to in the beginning of lesson 14. I’ll attempt to trounce that challenge with this app before continuing the series and I’ll elaborate on that separately. I’ll essentially attempt a few of his challenges at the end of lesson 23 as well, albeit with the app I am building. Naturally, I could begin smaller, i.e. building a variant of the “PetSounds” app, and persist from there. Although, I visualize that I would be able to do that easily enough.

Learning is half the fun

Packages, like the Coding4Fun Toolkit package and the Json.NET package are an invaluable resource along with the NuGet application-level package manager extension for Visual Studio. As for Json.NET, JSON and Json Data – all of which there was a referral to by Bob in lesson 21 – I didn’t get a palpable grasp of what either of them was and the use for them (other than the application of them in the SoundBoard app) as well as what Serialization and Deserialization implied. A few Bing queries afterward was enlightening (hint: underlined text == link). MSDN has a helpful article – albeit from 2002 – on Object Serialization in .NET and Windows Phone Dev Center has a topic on Serialization as well. Part 11 of Windows Store apps for Absolute Beginners with C# will probably clarify Json Data even further when I eventually get to that series. Thus, these packages, or Open Source libraries, with their preprogrammed Classes and Methods, have you building apps with littlest effort and with outright haste.

Lastly, Kudos to Clint Rutkas.

WP8 Development 1-5

I have gleefully finished part 1 through 5 of Channel 9, Windows Phone 8 Development for Absolute Beginners.

Windows Phone Emulator

A virtual Windows Phone device.

Installation and requirements

As you install the Windows Phone SDK (SDK 8.0), Microsoft Visual Studio Express 2012 for Windows Phone goes with it, both of which are free. It has a different layout to Microsoft Visual Studio Express 2013 for Windows Desktop, intelligibly. Thence, I now have both. There are system requirements for the former, which are Windows 8.1 Pro (or 8.0 Pro) 64-bit OS and an x86-64 CPU with either AMD or Intel Virtualization (AMD-V and VT-x respectively) and to have the BIOS or UEFI setting of that technology set to enabled) as the Windows Phone Emulator will use Hyper-V hardware virtualization. If you have any Intel Core i3/i5/i7 (nearly all Core 2) or AMD Athlon II, Phenom, Phenom II or FX processor, you are O.K.

XHTML, HTML, XAML, SGML, XML … WTH.

My previous knowledge of HTML and CSS, specifically XHTML have been an asset as to grasping XAML. You have Elements and Attributes in XAML too (although termed Objects and Properties), recognizable from XHTML and HTML as well as the familiar syntax and structure. There are subtle differences as well of course, for instance, the lowercase tags of XHTML as opposed to case-sensitive CamelCase of XAML. While HTML is a derivative of SGML and XHTML is a derivative of XML – which is also a derivative of SGML – XAML too is a derivative of XML and the sum of fundamental knowledge of each, does coalesce into a revelation with a newfound grasp on – and an awareness of – markup language, namespaces, procedural programmingdeclarative programming and well-formedness that I didn’t have prior. Bob Tabor suggested to learn either of HTML vs. XHTML and CSS in the concluding thoughts to the C# Fundamentals: Development for Absolute Beginners series and it is already apparent as to why. XML itself has become increasingly compelling too. Eventually, I’ll do the HTML5 & CSS3 Fundamentals: Development for Absolute Beginners series as well. I am enthralled by C#, XAML and Visual Studio.
