Application developers spend over 30% of their time implementing relational database access in object-oriented applications. The Object Persistence Framework for .Net provides a solution for simple and complex persistence scenarios.

You're probably looking at this page because one day you had the same questions:

•  How will I persist my Domain Objects in a application developed using .NET Framework?
• Can I wait until Microsoft or someone else develops a persistence framework?
• Is it possible to develop my applications with ObjectSpaces in mind and hope that Microsoft will deliver according to my timeframe?
• Could/Should I implement a persistence framework?

The question is how to solve your problem in a way that satisfies the expectation that all
of us have in mind. The OPF.NET objectives are:

• Develop a micro-kernel of a persistence framework that could be used by itself.
• Support high-levels apis like ObjectSpaces (when it becomes available)
