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.

Creating a log as text


In this recipe, we will be creating a .NET Standard 2.0 library that writes a text file as a log file. This log file will contain simple text entries of operations we do in an application. It will also demonstrate the use of command-line tools that come under the .NET Core SDK to create a solution and add projects as we move on.

Getting ready

Make sure you have installed Ubuntu 16.04 and .NET Core 2.0 SDK. If not, please follow the previous recipe to do so. Assuming everything is installed and .NET Core 2.0 is up and running, let's get started on creating the library that writes logs as text.

Make sure you have downloaded and installed Visual Studio Code from https://code.visualstudio.com. It's a straightforward installation of a .deb file from the site.

How to do it...

  1. Open the terminal.
  2. Now in your home directory or any other directory type the following command and press Enter:
$ dotnet new sln -o Chapter3 -n Chapter3.LogFile
  1.  Now, change to the newly created directory...
