A.Data is a simple framework for storing data used by .NET client apps. It uses standard XML serialization methods for persisting data, C# structures for defining structure of a data item, and the generic List<> for storing the structure objects. The serialized XML is analogous to the database file, the List<> is analogous to the data table, and the struct is a row in the data table.
The framework is published as a Visual Studio project template with a wizard for defining the file location and the struct name. The source code for the A.Data.Database.dll assembly, which contains a class (called A.Data.Database, incidentally) that provides standard Database functions to the Database class in the project. Also, the code for the Wizard is included for customization and improvement purposes.
