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.

Interop with existing native and Mono libraries


Code reusability is one of the key principles in programming. For example, in an application we may use a certain functionality multiple times, so we keep it in a useful place and refer it from that place, whenever we need it in our application. Now, suppose our application implemented some common functionality which we can use in other applications, in this case, instead of writing the same logic again, we can create a library. It is easily distributable and reusable.

Asp.NET Core supports cross-platform programming, so any Linux user who has built many reusable libraries, API-like console support, and filesystem access, and wants to use them while writing code in ASP.NET Core, can access them. In this section, we will see how to access these native libraries (.dll) and Mono libraries (.so) in the program.

Common Language Infrastructure (CLI) helps to interoperate with existing code. We need to handle three basic problems to get things to work...
