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

Building web services using ASP.NET Core Web API

Although HTTP was originally designed to request and respond with HTML and other resources for humans to look at, it is also good for building services. Roy Fielding stated in his doctoral dissertation, describing the Representational State Transfer (REST) architectural style, that the HTTP standard defines the following:

  • URLs to uniquely identify resources
  • Methods to perform common tasks, such as GET, POST, PUT, and DELETE
  • The ability to negotiate media formats, such as XML and JSON

Web services are services that use the HTTP communication standard, so they are sometimes called HTTP or RESTful services.

Understanding ASP.NET Core controllers

To allow the easy creation of web services, ASP.NET Core has combined what used to be two types of controller.

In earlier versions of ASP.NET, you would derive web services from ApiController to create a Web API service and then register API routes in the same route table that MVC uses.

With ASP.NET Core, you...
