Overview of this book

The .NET Standard is a standard that represents a set of APIs that all .NET platforms have to implement, making it easy for developers to access and use one common library for their development needs. This book begins with a quick refresher, helping you understand the mechanics of the new standard and offering insight into how it works. You’ll explore the core library concepts, such as working with collections, configurations, I/O, security, and multithreading. You’ll explore the iOS and Android libraries of Xamarin and we’ll guide you through creating a .NET Standard 2.0 library, which you’ll use with both Android and iOS applications. In the final chapters, you’ll learn the various debugging and diagnostics tools to deliver quality libraries and create a NuGet package of the .NET Standard 2.0 library. By the end of this book, you’ll be able to expand your current workflow to various .NET flavors and have the essential skills to create a .NET Standard 2.0 library from scratch to package and deliver it to the world.

Processing an XML file using LINQ to XML


In this recipe, we will be building a .NET Standard 2.0 library that reads XML data using LINQ to XML. LINQ to XML is a LINQ enabled in-memory programming interface. It enables you to work with XML using your favorite .NET language. C# is used in this book to describe the code. In this recipe, we will mainly be looking at querying an XML document using LINQ to XML. We have used LINQ to XML to write to an XML file in the A library that reads and writes to an XML file recipe.

Getting ready

This recipe assumes you have used LINQ. We are focusing on LINQ with XML documents. Let's fire up Visual Studio and get started.
