Open Source C# Object-Relational Mapping (ORM) Software

Catharsis.Repository .NET library provides abstraction over persistent data storages by introducing commonrepository pattern interfaces over popular ORM frameworks (NHibernate, Entity Framework, LINQ2SQL), as well as their implementations. Target : .NET Framework 4.0 NuGet package : https://www.nuget.org/packages/Catharsis.Repository The following ORM frameworks are supported at this time : 1. NHibernate 2. Entity Framework 6 (Database-First/Code-First approaches) 3. LINQ to SQL

Extensible repository and context-per-request infrastrucuture for .NET projects using Entity Framework.

FFEntityFramework is an Object-Relational Mapping Framework (O-R Mapping / Object Persistence) for .NET with built-in features like Xml-Serialization, Model-View-Controller-Framework or UndoManagement ... All these Components use the same Meta-Base which can be definied via Attributes (Annotations) on your Business-Classes. Nevertheless differences between Xml- and Db-Serialization can be made via an enum MetaUsage (Database, Xml, Internal …). For Example you can define a Key-Column which is only used for Db-Serialization and excluded for Xml-Serialization. The same can be done with References, Delegations &c. A special Feature is that all Metadata can be read from a comfortable Object-Model (MetaLayer) for your own needs.

An Enterprise Application Framework for .Net that produces an agile application from the data layer through to the front-end. Free open source under the LGPL license, it includes ORM and UI generation to create one application for the desktop & web. Please note that the primary source repository is now at https://github.com/Chillisoft/habanero

Open Jungo is a flexible entity persistence model that makes it easy to create object-centric components with minimal coding. Unlike most current entity frameworks, Jungo does not require developers to structure their code in any particular way or specify database structures. Open Jungo supports most major proprietary and open source databases as well as well as a built-in highly efficient zero-configuration object-oriented database systems. It requires no external dependencies and works with all current .Net and Mono frameworks.

The Tenor Framework is a set of utilities to improve development of web projects, although it can be used on desktop projects. The main goal is to simplify mapping relational tables to entities, in a simple and maintainable way.

Yet Another Persistance System is a framework for object persistance in C# that stores wide class of C# objects into a relational database without a need for ANY REDUNDANT CODING, such as object-table maping, writing SQL commands etc.

doPersistence is a C# dll that persists any object to any database. Will save directly to tables with dynamic Sql or it will map to stored procedures (store, load, delete, list). For single objects add a class attribute: [Persistable("Customer", "CustomerId", true)] public class Customer { ... For list objects, inherit from a generic list: public class CustomerList : PersistentList<Customer> Bulk storage is extremely fast with data pagination available on loads. ~10,000 objects/second. ~2,000 objects/second if loaded one row at a time.
