Wilson ORMapper for .NET v4.0 Review

Wilson ORMapper for .NET is an O/R Mapping library that transparently persists your business objects according to the rules defined in an XML mapping file. To use Wilson ORMapper from Visual Studio .NET, you add a project reference to the WilsonORMapper.dll file. After you have written the code for your classes and created your mapping file for those classes, you create an instance of the ObjectSpace class from the Wilson.ORMapper namespace, and pass the path of the mapping file, a connection string, and the type of database provider you want to use to the ObjectSpace constructor. From there, persisting your object is as easy as calling methods like PersistChanges() to save an object or GetObjectSet() to retrieve a series of objects. Wilson OR Mapper for .NET supports Microsoft SQL Server, Oracle, Microsoft Access, and ANSI compliant database systems. Support for Wilson ORMapper is provided via forums on the vendor's Web site and you can also e-mail the vendor with questions.
