C# 7 and .NET: Designing Modern Cross-platform Applications

By: Mark J. Price, Ovais Mehboob Ahmed Khan

Overview of this book

C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. The language is used to create desktop apps, background services, web apps, and mobile apps. .NET Core is open source and compatible with Mac OS and Linux. There is no limit to what you can achieve with C# and .NET Core. This Learning Path begins with the basics of C# and object-oriented programming (OOP) and explores features of C#, such as tuples, pattern matching, and out variables. You will understand.NET Standard 2.0 class libraries and ASP.NET Core 2.0, and create professional websites, services, and applications. You will become familiar with mobile app development using Xamarin.Forms and learn to develop high-performing applications by writing optimized code with various profiling techniques. By the end of C# 7 and .NET: Designing Modern Cross-platform Applications, you will have all the knowledge required to build modern, cross-platform apps using C# and .NET. This Learning Path includes content from the following Packt products: • C# 7.1 and .NET Core 2.0 - Modern Cross-Platform Development - Third Edition by Mark J. Price • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan

What are data structures?


A data structure is a way of storing and unifying data in such a way that operations on that data can be performed in an efficient manner. The data can be stored in several ways. For example, we can have a Person object that contains a few properties, such as PersonID and PersonName, where PersonID is of the integer type andPersonName is of thestring type. ThisPersonobject stores the data in memory, and can be further used to save that record in the database. Another example is an array called Countries of the string typethat contains a list of countries. We can use the Countriesarray to retrieve a country name and use it in a program. Therefore, any type of object that stores data is called a data structure. All primitive types, such as integers, strings, chars, and Booleans, are different types of data structure, whereas other collection types, such as LinkedList,ArrayList,SortedList, and others, are also types of data structure that can store information in exclusive...
