This book focuses on providing Java programmers with the information they need to write applications for the Microsoft .NET platform using C#. The first hurdle in becoming proficient with the .NET platform is to understand the basics of the .NET initiative. Understanding the goals, structure, and capabilities of .NET provides programmers with a context through which they can better understand the detailed technological discussions presented in later chapters of this book. We start this chapter by providing background information that has driven and shaped the .NET initiative. We then discuss the goals, scope, and structure of .NET. Finally we give a summary of the migration and integration options when dealing with Java and .NET.

So now, let s put this together to see how C# uses these different IL instructions:
