Wei-Meng Lee has a fantastic post on devx describing how to manage data in .NET mobile applications. I had a particularly hard time trying to gather information on this topic and his tutorial on using XML serialization to generate custom user configuration files was just what I was looking for :-)

The article covers:

Introduction - Storing Simple Data in Text Files

SQL Server Compact 3.5 Database - Storing Complex Data

Creating a SQL Compact Edition Database Programmatically

XML - Configuration Files Using XML Serialization

Thanks Wei-Meng!!
