Summary
Before we get to the heart of our subject?Part II, "C# Class Fundamentals," and Part III, "Writing Code"?I thought it would be a good idea to have a "getting started" tutorial. In this tutorial, I'll take you on a quick tour of the development process for a simple C# application. First, I'll cover the advantages and disadvantages of the different editors you can use to write in C#. Once you've selected an editor, we'll write the canonical "Hello, World" example application to get to know the basic syntax and structure of writing C# applications. You'll see that as in most languages, this syntax is formulaic and you can use this application as a template to write most basic C# applications. You'll then learn how to compile using the command-line compiler, and you'll learn how to run your new application.
