Hands-On Mobile Development with .NET Core

Getting Started with .NET Core

.NET Core (previously known as .NET vNext) is the general umbrella term used for Microsoft's cross-platform toolset that aims to solve the shortcomings of centralized/machine-wide frameworks (NET framework) by creating a portable, platform agnostic, modular runtime and framework. This decentralized and modular development platform allows developers to create applications for multiple platforms using the common .NET base class libraries (NET standard), as well as various runtimes and application models, depending on the target platforms. This chapter will give you a brief introduction to .NET Core while explaining different tiers of .NET Core infrastructure. Languages and runtimes, as well as extensions that can be used together with .NET Core will be discussed and analyzed.

The combination of.NET Core, .NET Standard, and Xamarin is the...

Cross-platform development

The term cross-platform application development refers to the process of creating a software application that can run on multiple operating systems. In this book, we will not try to answer the question of why, but how – more specifically, will try to create a cross-platform application using the toolset provided by Microsoft and .NET Core.

Before we start talking about .NET Core, let's take a look at the process of developing an application for multiple platforms. Faced with the cross-platform requirement, the product team can choose multiple paths that will lead the developers through different application life cycles.

Throughout this book, we will have hypothetical user stories defined for various scenarios. We will start with an overall user story that underlines the importance of .NET Core:

"I, as a product owner, would...

Introduction to .NET Core

In order to understand the roots of and motivation for let us start with a quote:

"Software producers who maximize their product's potential for useful combination with other software, while at the same time minimizing any restrictions upon its further re-combination, will be the survivors within a software industry that is in the process of reorganizing itself around the network exchange of commodity data." 
-- David Stutz General Program Manager for Shared Source Common Language Infrastructure, Microsoft, 2004.

.NET Core dates back as early as 2001 when Shared Source Common Language Infrastructure (SSCLI) was shared sourced (not for commercial use) under the code name Rotor. This was the ECMA 335, that is, the Common Language Infrastructure (CLI) standard implementation. Rotor could be built on FreeBSD (version...

.NET Foundation

The .NET Foundation is an independent organization that supports open source development and collaboration within the .NET ecosystem. The .NET foundation supports the development of active projects within the ecosystem by evangelizing the technologies through organizing/sponsoring meetups and by active involvement in community-driven projects.

The .NET Foundation portfolio grew especially large due to the projects that were brought in by the acquisition of Xamarin.

Notable .NET Foundation projects

Some of the most notable projects that are generally used in modern .NET applications, as well as cross-platform mobile applications, are as follows:

  • .NET Core
  • ASP.NET Core
  • Roslyn
  • Reactive Extensions
  • Entity...

Developing with .NET Core

.NET Core applications can be developed with Visual Studio on the Windows platform and Visual Studio for Mac (inheriting from Xamarin Studio) on macOS. Visual Studio Code (an open source project) and Rider (JetBrain's development IDE) provide support for both of these platforms, as well as Unix-based systems. While these platforms provide the desired user-friendly development UI, technically, .NET core applications can be written with a simple text editor and compiled using the .NET Core command-line toolset:

As we mentioned previously, the only intrinsic runtime in the .NET Core CLI is the .NET Core runtime, which is primarily used for creating console applications with access to the complete base class library.

Without further ado, let's create our first cross-platform application with the CLI tools and see how it behaves on multiple target...

Summary

The .NET ecosystem is growing at an exponential velocity with the new, open-source oriented approach being adopted by Microsoft. Various runtimes and frameworks are part of community-driven projects that cover bigger portions of the original .NET framework which was, ironically, destined to be part of Windows itself.

Using the .NET Core infrastructure and the provided runtimes, developers can, nowadays, develop applications for mobile platforms such as iOS, Android, and UWP, as well as micro runtimes such as Windows IoT Core, Raspbian, and Tizen. Setting device-specific runtimes aside, Azure and web development can also be accomplished using .NET Core.

In the remainder of this book, we will be implementing a Xamarin.Forms application using the Mono runtime and creating a web infrastructure composed of Serverless (Logic Apps and Functions) components, as well as ASP...

The book starts with giving a little bit of theory with simple "experiments". In the later chapters, a step by step implementation is outlined for a mobile application using Xamarin and the azure infrastructure with different resources mostly created using .net core.

Great overview for any experienced programmers who don't know Xamarin.Well written and informative, each chapter gives a nice overview of a topic, gets one started writing real code, but thankfully doesn't try to be exhaustive. Each technology's main features and concepts are covered enough to get started. Its amazing how much ground he covers. The book got rid of any worries I wasn't using the right technology for the right problem!

Libro terribile, impossibile seguire passo passo quello che viene detto, non solo perché di fa riferimento a informazioni obsolete, ma anche per il modo con il quale vengono trattati gli argomenti.Ne ho fatto il reso.

This is a confusing book!Much details are given about the framework information which seemed almost word for word on what you can find on the MS website. To me this was a waste of space as this information is already there and in many cases not nessary when writting apps.The other part that is annoying is that your exerices are not clearly explained, this by no means is an advance book for developers so explaining where the code has to go and even what to name it would have been a great help for those that are trying to learn another espect of the Visual Studio IDE.It almost seems like there are missing pages as it doent explain the actual programming side of the lessons,My advice keep hunting find another book.

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
