As far as I can tell, there is almost nothing out there yet. You might want to check out Objectspaces (http://communities.microsoft.com/newsgroups/default.asp scroll down to the Objectspaces newsgroup) which provides a framework for persisting your data objects. From what I see, you still have to create a base Abstract class for Business objects.

Here is a description of Objectspaces from Microsoft:
"Microsoft ObjectSpaces are a set of classes and interfaces that enable you to treat data as an object (or objects), independent of the underlying data store used by an application. The ObjectSpaces architecture builds on the existing data access and XML APIs within the Microsoft .NET Framework (System.Data, System.Xml) to provide access to relational and XML data sources such as Microsoft SQL Server®, OLE DB, or XML files. The ObjectSpaces architecture also provides access to in-memory relational and XML data such as the DataSet.

The ObjectSpaces architecture enables you to expose data as objects and lists of objects rather than as tables, columns, rows, or XML elements. Objects defined within the ObjectSpaces architecture are known as "persistent objects", and are defined using standard .NET Framework conventions in such a way that the ObjectSpaces architecture can manage them with a specified data store. Once you have defined a persistent object, you use an ObjectSpace to create instances of the object and to persist the object data to a data store, as well as to delete instances of the object from the data store.

Using this approach, you can expose the functionality of the component in way that makes the most sense for your particular business applications. A single business logic component can then be compiled into its own assembly and reused by any variety of applications. Also, the clients do not necessarily need to be aware of the ObjectSpaces architecture. They could merely consume custom classes that return persistent objects or lists (IList) of persistent objects.
