CMS Companion eBook Available Beginning ASP.NET in VB 2010 Matthew MacDonald, Author of Pro Silverlight in VB Pro WPF in VB 2010 Pro ASP.NET in C# 2010 ASP.NET: The Complete Reference Welcome to the most up-to-date and comprehensive beginning ASP.NET book you’ll find on any shelf As you probably already know, ASP.NET is a framework for developing modern web applications In the right hands, ASP.NET produces web applications that are secure, blisteringly fast, and highly scalable Best of all, ASP.NET includes a huge set of ready-to-use features like website navigation, data binding, themes, and user management ASP.NET allows you to create everything from a dynamic personal website to a full-scale e-commerce storefront In this book, I assume that you have only basic knowledge of VB, although those coming from a more experienced background will find that the basics are reviewed quickly and efficiently As you explore ASP.NET, you’ll learn the key database, security, and performance principles you need to know in order to design a solid web application My book will also teach you to use techniques such as object-oriented programming and code-behind development from the beginning, rather than fake it with simplified techniques that won’t work well in real life Once you’ve reached the end of the book, you will have mastered the core techniques of website programming, and you’ll have the knowledge necessary to begin work as a professional ASP.NET developer THE EXPERT’S VOICE ® IN NET Beginning ASP.NET in VB 2010 Start your journey with the fundamentals
