Not long ago, I wrote a post about how to build an N-Tier application with WCF and Datasets in Visual Studio 2008.
We've known ADO.Net DataSets since the day we started developing data centric applications with the .Net Framework. In the early days of Visual Studio 2003 we have designed DataSets using the XSD designer and had to program the Data Access Layer ourselves. Visual Studio 2008 brings many enhancements to DataSets, which help us to create data centric applications easier than ever. This post is a step by step guide for building an N-Tier application with WCF and DataSets in Visual Studio 2008 that shows all the new enhancements throughout it.
