Introduction
CrystalMapper is a very simple object ORM, it support Linq queries. CrystalMapper written to compete with ADO.NET DataSet fetch speed. It is very fast compare to other ORMs.
Examples of search, update ... are shown at
http://csharplive.wordpress.comIt is fast because it does not do any heaving loading task all by itself, instead leaves it to object for filling itself up when ask by CrystalMapper. Don’t you worry about writing code for manually filling data into objects, CrystalMapper include Templates for generating classes and it is integral part of ORM. Templates are written for CodeSmith (A code generator tool). I know it is not Open Source but until I found some easy open source code generator tool, please bear with it. You can use trial versions of CodeSmith for now (http://www.codesmithtools.com).

But any entity or its collection in Crystal Mapper can be update able from different thread than UI thread, this is possible due to event class (DispatchedEvent) provided in CoreSystem Class Library: http://coresystem.codeplex.com)
