Visual Basic

Excerpt from Visual Basic 2008 Programmer's Reference

WPF applications are similar in concept to Windows Forms applications in many respects. Both display a form or window that contains controls. Controls in both systems provide properties, methods, and events that determine the control's appearance and behavior.

Windows Forms applications use a set of controls provided by the System.Windows.Forms namespace. WPF applications use a different set of controls in the System.Windows.Controls namespace. Many of these controls serve similar functions to those used by Windows Forms applications, but they provide a different set of capabilities. For example, both namespaces have buttons, labels, combo boxes, and check boxes, but their appearances and abilities are different.

Many of the newest features in Visual Studio 2008 were added to support LINQ (Language Integrated Query). Extension methods, lambda functions, anonymous types, and many of the other features new to Visual Studio were added to make building LINQ easier.

Visual Basic doesn't really execute LINQ queries. Instead it converts them into a series of function calls that perform the query. While the LINQ query syntax is generally easier to use, it is sometimes helpful to understand what those function calls look like.

The following sections explain the general form of these function calls. They explain how the function calls are built, how you can use these functions directly in your code, and how you can extend LINQ to add your own LINQ query methods.
