LINQ to XML Instead of a Database
When people think of having to store data for their applications, a database such as SQL Server immediately comes to mind. However, XML files are very handy for storing data without the overhead of a database. Using XML files to cache often-used, but seldom changed data such as US state codes, employee types and other validation tables can avoid network roundtrips and speed up your application. In addition, XML files are great for off-line applications where a user needs to add, edit and delete data when they can’t connect to a database.

Twitter Programming Using WCF and REST
Along with an easy site with which you can access your account, there are many really cool Twitter clients out there. This is thanks to an exposed API that you can use to access all of Twitter’s features. The great thing is that this API uses a technology that WCF has embraced completely; I’m talking about REST. Though you can certainly use straight network programming to access and update your Twitter account, why not use the technology that Microsoft has put all their eggs into as far as communications programming is concerned? Twitter is, after all, all about communicating, right?

Sharpening Your Axis with Visual Basic 9
Visual Basic 9 in Visual Studio 2008 has a new set of language features that allows developers to work with XML in a much more productive way using a new API called LINQ to XML. LINQ stands for Language Integrated Query and it allows you to write queries for things like objects, databases, and XML in a standard way. Visual Basic provides deep support for LINQ to XML through what’s called XML literals and XML axis properties. These features allow you to use a familiar, convenient syntax for working with XML in your Visual Basic code. LINQ to XML is a new, in-memory XML programming API specifically designed to leverage the LINQ framework. Even though you can call the LINQ APIs directly, only Visual Basic allows you to declare XML literals and directly access XML axis properties. This article will help you master these new features for working with XML in Visual Basic.

Browsing Windows Live Expo with LINQ to XML
LINQ to XML, which makes query a first class construct in C# and Visual Basic, is the new XML API in the .NET Framework 3.5. With the introduction of Language Integrated Query (LINQ), Microsoft is introducing LINQ implementations that work over objects, data, and XML. LINQ to XML improves on System.Xml in the .NET Framework 2.0 by being both simpler to use and more efficient. Microsoft developed this new API because the W3C-based DOM API does not integrate well into the LINQ programming model.

Making Sense of the XML DataType in SQL Server 2005
Updated
As database developers, many of us have had to dip our feet into the wide ocean of XML.It should come as good news that in SQL Server 2005, you can store XML in the database with a new XML datatype. Although this is good news, many developers have been storing XML in the database for some time now. Without implicit support for XML, developers have been shoving XML documents into text fields since XML’s inception.

System.Transactions and ADO.NET 2.0
Updated
Data is the blood in your system; it sits in its comfortable home of a database, and camps out in the tent of XML, but it deserves to be worked with in a reliable and consistent manner.But why should only data-related operations be reliable? Shouldn’t you want to write reliable code for your other operations? The introduction of System.Transactions in .NET 2.0 brings a paradigm shift of how you will write reliable transactional code on the Windows platform. This article dives deep in the depths of how System.Transactions works, and how you can use it to your advantage. You will also see how you can leverage existing System.Transactions integration within ADO.NET, and why you need to really understand what is under the magic carpet.

LINQ
ByMarkus Egger
CODE Magazine · 2006 - March/April · Markus Egger Talks Tech · VFP Conversion Papers
Updated
At PDC 2005, Microsoft introduced brand new technology known as LINQ, which stands for “Language Integrated Query.”The feature-set hiding behind this acronym is truly mind-boggling and worthy of a lot of attention. In short, LINQ introduces a query language similar to SQL Server’s T-SQL, in C# and VB.NET. Imagine that you could issue something like a “select * from customers” statement within C# or VB.NET. This sounds somewhat intriguing, but it doesn’t begin to communicate the power of LINQ.

Using XML For Messaging In Distributed Applications (Part 2)
Updated
Rick Strahl argues that XML can serve as a practical, low-effort backbone for distributed application messaging, enabling seamless data and object transfer between client and server with minimal code. He showcases a free Visual FoxPro tool, wwXML, to convert tables and nested objects to and from XML, generate hierarchical XML from complex objects, and move data over HTTP (including POST). By decoupling client and server through XML, supporting DTDs, and enabling offline/online synchronization, Strahl demonstrates a concrete path to interoperable, cross-platform data exchange and remote object persistence.

XML Data Binding for IE5 clients
Updated
Jon Newell advocates using XML as the data transport to bind server data to HTML in IE5+ client applications, separating content from presentation to enable multi‑platform reach and better scalability. By embedding XML data islands in server responses and using nonstandard yet IE‑friendly attributes (XMLTABLE, XMLFIELD) on form elements, data is bound on the client via a lightweight JavaScript library (binddata), with an optional sync back to XML islands and easy posting back to the server. This approach promotes true N‑Tier separation and interoperability across fat, thin, and mobile clients.
