Summary

This is a practical introduction to the fundamentals of .NET Web development for experienced programmers who are now learning .NET. Using rich code examples, this book covers the entire process of .NET Web development, and all the relevant technologies, from ASP.NET to XML. The authors offer a concise review of traditional Web development, then demonstrate the value .NET adds for those building advanced Web applications and services. After introducing .NET's key languages, they present a straightforward migration path from current technologies to ASP.NET, ADO.NET and VB.NET. Coverage includes: .NET framework and architecture; the role of XML, SOAP, and UDDI in .NET development; new techniques such as object remoting; and interoperability with non-.NET systems. The book's key concepts are tied together through a case study that is shared by other books in this .NET series from Object Innovations and Prentice Hall PTR -- giving readers a jumpstart when they're ready for other books in the series.
