Description: This article begins a series. The first three articles explain the fundamentals of XPath queries, XSD schemas, and XSLT. The following articles look at how well these standards are supported by the .NET framework and what are the most important namespaces and types. This series of articles is not intended as a comprehensive description of all the .NET types around XML. The goal, rather, is to provide a good introduction so you understand the XML capabilities of the .NET framework and can start leveraging them for your current .NET projects.
