The code in this book has been verified to work against Microsoft Visual Studio 2005 Professional, and therefore against version 2.0 of the .NET Framework. The database is a SQL Server Express database, and SQL Server Express is included with Visual Studio 2005 Professional. The Enterprise version of VS 2005 and the full version of SQL Server are useful, but not necessary. In order to run the tools and products listed previously, you ll need at least one PC with Windows 2000, Windows Server 2003, or Windows XP Professional Edition installed. To test CSLA .NET s support for multiple physical tiers, of course, you ll need an additional PC (or you can use Virtual PC or a similar tool) for each tier that you wish to add.

Code has several fonts. If I m talking about code in the body of the text, I use a fixed-width font like this: foreach. If it s a block of code that you can type as a program and run, on the other hand, then it will appear as follows: if (Thread.CurrentPrincipal.Identity.IsAuthenticated) { pnlUser.Text = Thread.CurrentPrincipal.Identity.Name; EnableMenus(); } Sometimes, you ll see code in a mixture of styles, like this: dgProjects.DataSource = ProjectList.GetProjectList(); DataBind(); // Set security System.Security.Principal.IPrincipal user; user = Threading.Thread.CurrentPrincipal; When this happens, the code with a normal font is code you re already familiar with, or code that doesn t require immediate action. Lines in bold font indicate either new additions to the code since you last looked at it, or something that I particularly want to draw your attention to.

CHAPTER
Distributed Architecture
bject-oriented design and programming are big topics there are entire books devoted solely to the process of object-oriented design, and other books devoted to using object-oriented programming in various languages and on various programming platforms. My focus in this book isn t to teach the basics of object-oriented design or programming, but rather to show how they may be applied to the creation of distributed .NET applications. It can be difficult to apply object-oriented design and programming effectively in a physically distributed environment. This chapter is intended to provide a good understanding of the key issues surrounding distributed computing as it relates to object-oriented development. I ll cover a number of topics, including the following: How logical n-tier architectures help address reuse and maintainability How physical n-tier architectures impact performance, scalability, security, and fault tolerance The difference between data-centric and object-oriented application models How object-oriented models help increase code reuse and application maintainability The effective use of objects in a distributed environment, including the concepts of anchored and mobile objects The relationship between an architecture and a framework This chapter provides an introduction to the concepts and issues surrounding distributed, objectoriented architecture. Throughout this book, you ll be exploring an n-tier architecture that may be physically distributed across multiple machines. The book will show how to use object-oriented design and programming techniques to implement a framework supporting this architecture. After that, a sample application will be created to demonstrate how the architecture and the framework support development efforts.
