Karvonite

Karvonite is an object persistence framework for the .NET platform. Karvonite's goal is to relieve the developer from all serialization related programming tasks in a non-invasive way. It can save you from writing a lot of boring and thus error-prone code for moving the in-memory objects to and from the data storage. The Karvonite API is very simple and provides a gradual learning curve with a very low entry point.
Despite the fact that .NET serialization and XML files are ideal for storing data easily and effectively, in several cases they are not a viable replacement for a data engine. In contrast, not all applications require the horsepower and the excessive functionality and optimization of an enterprise database or a SQL engine; databases are a skill unto themselves and the learning curve is not as fast as expected.
