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.

CSV, HTML, JSON, and XML data

In F# applications and scripts, FSharp.Data.dll is used to implement the functionality to access data. It is also useful for structured file formats such as JSON, XML and for consuming freebase services. A sample document structure is used for type safe access to the document; it works as a type provider, like the CSV type provider takes a CSV sample as input and creates a column format data for that sample.

Providers

F# supports different types of provider, such as:
