RepoDB
A hybrid ORM library for .NET.
RepoDB is an open-source .NET ORM library that bridges the gaps of micro-ORMs and full-ORMs. It helps you simplify the switch-over of when to use the BASIC and ADVANCE operations during the development. Like with any other ORMs, RepoDB does provide the preliminary methods needed for your basic operations. The good thing is, it also does provide the operations that are needed to cater your edge-cases like 2nd-Layer Cache, Tracing, Repositories, Property Handlers, and Batch/Bulk Operations. If you are to use RepoDB, your development experience is as simple as opening a connection and calling the advanced operations with a very minimal code. It is the reason that makes this library the simplest ORM to use. When you do the bulk operations, the generated value of the identity columns will be set back to the data models, just right after your execution. It is an important use-case that is/may needed by you and/or most developers. -

Beam
A type-safe, non-TH Haskell SQL library and ORM
Beam is a Haskell interface to relational databases. Beam uses the Haskell type system to verify that queries are type-safe before sending them to the database server. Queries are written in a straightforward, natural monadic syntax. Combinators are provided for all standard SQL92 features, and a significant subset of SQL99, SQL2003, and SQL2008 features. Beam is standards-compliant but not naive. We recognize that different database backends provide different guarantees, syntaxes, and advantages. To reflect this, Beam maintains a modular design. While the core package provides standard functionality, Beam is split up into a variety of backends which provide a means to interface Beam's data query and update DSLs with particular RDBMS backends. Backends can be written and maintained independently of this repository. For example, the beam-MySQL and beam-firebird backends are packaged independently. -

CCM (C# Collections Mapper)
The CCM is a mini ORM, working with the database and C# collections
CCM is a solution for the data management layer in the combination of Sql Server with a C # application. In whole this is a strongly typed entity mapper projecting the application's business logics onto database tables using T-SQL stored procedures. CCM allows you to implement fairly complex data structures in your application, without bothering about difficult and tedious questions of data acquisition and conversion issue, allowing you to pay more attention to the develop of business logic and UI. There no need to worry about migrations, context, etc. At the same time, ORM completely relieves the developer from direct communicating with ADO - datasets, tables, rows, and other data aceess component, to track connections, commands or operate with adapters because ORM works at a higher level of data abstraction. At the same time you will be completely protected from memory leaks and free to create complexity application logic at the primary data level. -

Catharsis.NET.Repository
.NET library that provides abstraction over persistent data storages.
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 -

Chloe
A lightweight and high-performance Object/Relational Mapping(ORM)
Chloe is a lightweight Object/Relational Mapping(ORM) library. The query interface is similar to LINQ. You can query data like LINQ and do any things(Join Query | Group Query | Aggregate Query | Insert | Batch Update | Batch Delete) by lambda with Chloe.ORM. Pay attention to splicing lambda expression trees by yourself, do not wrap your variables with ConstantExpression, otherwise, non-parameterized sql will be generated, and there is a risk of sql injection! If the entity does not explicitly specify any auto-increment columns and the primary key is of type Int16, Int32, or Int64, the default primary key is the auto-increment column. If it is not an auto-increment column, it needs to be marked with the attribute NonAutoIncrementAttribute. -

ThinORM
A lightweight ORM that does not require annotations.
This project was the result of working on systems constrained to versions of Java < 1.5 and including a great deal of code dealing with object persistence. This project was essentially a proof-of-concept to determine whether or not I could create, essentially, an alternative to JPA that did not rely on annotations. I was able to create a working system, and a fairly lightweight one at that, but it would require a great deal of work to be production ready. -
