"Streamline Mapping With Orcas and LINQ" by Roger Jennings
Visual Studio Magazine, December 2005

Readme.txt File for LinqTest Visual Basic 9.0 LINQ and XLinq Demonstration Projects (LinqTestConsoleVB.sln and XLinqTestWinFormVB.sln)

The two sample projects have the following prerequisites:

1. Installation of Visual Studio 2005 or Visual Basic Express RTM version (8.0.50727.42).

2. Visual Basic LINQ Tech Preview (LINQ VB Preview.msi) downloaded from http://msdn.microsoft.com/netframework/future/linq/ on 11/2/2005 or later. (Earlier versions 

3. For LinqTestConsoleVB.sln, SQL Server 2000, MSDE 2000, or the SQL Server 2005 or SQL Express RTM version. You must install the Northwind sample database with the Instnwnd.sql script to your current instance.

This LinqTest.zip file contains the two sample XLinq projects, so extract the files with the full path to d:\LinqTest subfolders.

LinqTestConsoleVB.sln is a console application that emulates DLink mapping of the Northwind Customers, Orders, and Products files to simple business objects. The application replaces C# 3.0 with VB 9.0 code for several LINQ examples.

XLinqTestWinFormVB.sln is a Windows Form application that demonstrates how to use VB 9.0 to create XML business documents with three different approaches. For more information about this project, go to http://oakleafblog.blogspot.com/2005/10/compose-xml-content-with-xlinq.html.

An updated version of these projects will be available after the VB 9.0 Tech Preview gains Dlinq capabilities similar to the C# 3.0 Tech Preview (expected in December 2005).
