Overview of this book

With the rise in the number of tools and technologies available today, developers and architects are always exploring ways to create better and smarter solutions. Before, the differences between target platforms was a major roadblock, but that's not the case now. .NET Core 2.0 By Example will take you on an exciting journey to building better software. This book provides fresh and relevant content to .NET Core 2.0 in a succinct format that’s enjoyable to read. It also delivers concepts, along with the implications, design decisions, and potential pitfalls you might face when targeting Linux and Windows systems, in a logical and simple way. With the .NET framework at its center, the book comprises of five varied projects: a multiplayer Tic-tac-toe game; a real-time chat application, Let'sChat; a chatbot; a microservice-based buying-selling application; and a movie booking application. You will start each chapter with a high-level overview of the content, followed by the above example applications described in detail. By the end of each chapter, you will not only be proficient with the concepts, but you’ll also have created a tangible component in the application. By the end of the book, you will have built five solid projects using all the tools and support provided by the .NET Core 2.0 framework.

A sample application to implement new library and ncurses


Now that we know the fundamentals, let's start building a sample application which implements ncurses. We will create a C# application which imports a C library or we can say .so file. This library has implemented ncurses functions. P/Invoke allows us to use those ncurses functions in our C# application.

First, we will create a C program which implements ncurses functions using an ncurses header. Let's create an application which takes an input character; this character will be printed in a window, based on the number of rows and columns the user enters from the application where we will import this library. The function drawCharOnWindow() prints the character, based on the number of rows and columns present in the window; it takes character, row, and column as input parameters. We get the size of the window using the ncurses function, getmaxyx(), and if the user enters q, it quits the printing of the character. Open Visual Studio...
