My 4th tutorial Displaying SQL Database Data in a DataGrid using LINQ and WCF is now available, as is the source code and a version of the tutorial in PDF
For the moment, I recommend the PDF version as the images are clearer. We're fixing up the HTML versions of all the tutorials even as I write this.
This tutorial walks through
- Creating a LINQ query against your SQL Server database
- Creating a WCF service to provide access to the results of your LINQ query
- Binding Silverlight 2 controls against the WCF service
We will, over time have a way to provide direct feedback for each tutorial, but for now, please do send email or use the forums to ask questions about anything you read in the tutorials.
