Takes a straightforward, hands-on approach to explain everything you need to know from development to deployment and maintenance for this platform-all from a developer's perspective. Softcover. CD-ROM included.

Chapter Organization

The book is divided into two parts. The first part, Chapters 1-5, focuses on the fundamentals of .NET Programming Model and shows how to develop .NET-based applications.
The second part, Chapters 6-10, focuses on the services provided by .NET. Each chapter focuses on a specific aspect of .NET. These chapters are largely independent of each other.

Chapter 1: What is .NET?
.NET is Microsoft's new initiative for building applications regardless of the platforms or languages in use. The .NET label applies to three distinct but related items: a vision for how information technology (IT) will evolve, a software platform to build .NET applications, and an application-hosting business designed to support the vision and market the platform. In this chapter, we inspect each of these items from a fairly nontechnical perspective. By the end of the chapter, the readers will have a good idea of where Microsoft is going with the .NET initiative and will understand the terminology, features, and services offered by the .NET Framework, the software platform for .NET applications.

Chapter 2: From C++ to C#
This chapter focuses on various stages of building .NET applications-from development to debugging and deploying. You will write simple C# programs to explore common programming paradigms under the .NET Framework. In the process, you will learn the differences and similarities between C++ and C#. By the end of the chapter, readers will understand many key concepts of the .NET Framework and will be fairly comfortable developing simple .NET applications using C#.

Chapter 3: Assemblies
Under .NET, assemblies form the fundamental building block of program components. In defining the format for the assembly, .NET had many goals. These goals included interoperability among different programming languages, side-by-side execution of multiple versions of the same assembly, performance enhancements, and so on. In this chapter, we take an in-depth look at the assemblies and examine how these goals were achieved. By the end of the chapter, you will have a good knowledge of the assembly internals and the packaging and deployment model under .NET.

Chapter 4: Essentials of the .NET Framework
In this chapter, we examine the facilities that the .NET Framework provides to load and execute the code and provide services to the executing code. We start with an overview of various components that constitute the .NET Framework. Then we look at the overall process of managed code execution. We will see how .NET applications can be administratively controlled using external configuration files and how the configuration mechanism can be extended to store custom settings. We then look at the type system used by the common language runtime and examine the memory and performance considerations of using reference types versus value types. We examine how the CLS provides for cross-language interoperability. We look at how the execution engine validates the metadata, verifies the MSIL code for type-safety, and performs JIT compilation on the MSIL code. Finally, we look at the automatic memory management features of the runtime and how it simplifies or complicates programming under .NET. By the end of the chapter, you will have a good understanding of .NET architecture and how it helps in producing robust applications that can potentially be reused by any programming language under .NET. You will also learn the strategies of generating efficient code.

Chapter 5: Programming with the Base Class Library
The .NET BCL includes hundreds of classes that provide a number of useful services to help developers boost their productivity. In this chapter, we look at how to solve many common programming tasks using these classes. By the end of the chapter, you will become familiar with many important classes under the .NET Framework.

Chapter 6: Distributed Computing
In this chapter, we look at how to develop distributed applications under .NET that can communicate within intranets as well as over the Internet. We will see how .NET remoting offers seamless remote activation and remote method calls, among other things. We examine how to develop intranet applications using this support. Over the Internet, Web services have become the building blocks for distributed Web-based applications. We will look at the support offered by ASP.NET to create and deploy Web services. By the end of this chapter, readers will be comfortable developing applications using the common language runtime object-remoting and will be fairly conversant with ASP.NET Web services development.

Chapter 7: Interoperability
The .NET Framework provides support for managed code to interoperate with unmanaged code. The unmanaged code could either be COM-based or be in native DLLs. The .NET Framework has been designed to provide smooth interoperability. In this chapter, we examine the support for interoperability provided by the .NET Framework. By the end of the chapter, readers will be comfortable making calls from managed code into unmanaged code and vice versa.

Chapter 8: Concurrency
Under Windows, and most other modern OSs, a process can execute multiple threads concurrently, each of which carry out a specific task. The .NET Framework supports developing multithreaded applications in two ways-by supporting the creation and use of threads and by providing a mechanism to make asynchronous calls. In this chapter, we examine both these techniques in detail. We also look at various issues involved with multithread programming and the support provided by the .NET Framework in developing classes that are safe from concurrent access.

Chapter 9: Security
The .NET Framework offers two security mechanisms-code access security and role-based security. Both security mechanisms are built on top of the security provided by the underlying OS. Code access security keeps track of where the assemblies come from and what security permissions should be granted to them. Role-based security enables the code to make security decisions based on the role of the user executing the code.

In this chapter, we look at the concepts underlying code access security and role-based security. We also examine the classes and services provided by the .NET Framework to facilitate the use of these security mechanisms.

Security is also an important consideration for ASP.NET applications. ASP.NET applications need to authenticate clients and provide restricted access to any sensitive data, based on the client credentials. In addition, the ASP.NET applications may also have to act on behalf of the client in some cases to access OS secured resources such as NTFS files. In this chapter, we also examine various security features that ASP.NET provides to deal with authentication, authorization, and impersonation.

Chapter 10: Enterprise Services
Enterprise system development has historically been a very time- and resource-consuming process. The development complexity arises from the extra enterprise-level requirements such as scalability, robustness, security, automatic transaction processing, and so on.

The .NET Framework provides many infrastructural services to meet the needs of enterprise systems. This allows businesses to focus on their core competencies instead of building the plumbing themselves.

In this chapter, we examine in detail some important requirements for enterprise systems and the services provided by .NET to meet these requirements.

A concise, no-nonsense book. All topics are cut to the chase. This book is for C++ and Java pros who want to master C# in the shortest time possible. I also have 3 other C# books. Only this one calms me down and gives me the joy of reading while learning. However, for people who is new to programming, I recommend "Learn to Program with C#" by John Smiley. My 3rd book, "C# in a Nutshell" is a good choice for reference. My 4th one, "Introduction to C# Using .Net" is good too, but the topics covered are not as broad as this one.

For donwloading this book's sample code, it points to www.phptr.com/tapadiya/dotnet/, which no longer works. Instead, go http://www.tapadiya.net/pradeep/ComPlusBook.htm#CodeSamples, a link I finally found after 10 minutes of Google search.
