AutoMapper
A convention-based object-object mapper in .NET
A convention-based object-object mapper. 100% organic and gluten-free. Takes out all of the fuss of mapping one object to another. AutoMapper is a simple little library built to solve a deceptively complex problem, getting rid of code that mapped one object to another. This type of code is rather dreary and boring to write, so why not invent a tool to do it for us? First, install NuGet. Then, install AutoMapper from the package manager console. AutoMapper is an object-object mapper. Object-object mapping works by transforming an input object of one type into an output object of a different type. What makes AutoMapper interesting is that it provides some interesting conventions to take the dirty work out of figuring out how to map type A to type B. As long as type B follows AutoMapper’s established convention, almost zero configuration is needed to map two types. -

CCG
CCG (Crud Class Generator) is a ORM tool for .Net
The Crud Class Generator tool was developed for .Net to generate the class, which is an object model of a database table. Thanks to these created classes, many CRUD operations can be performed without writing a SQL query. *CCG is easy to use, because; it is developer-friendly *CCG is practical, because; it allows to make many crud processes without writing SQL query *CCG is fast because; The object size is very small and allowing multiple simultaneous operations to be performed by going to the database only once. To get help about CCG please visit http://ccg.snazzydocs.com/ You can send your questions and suggestions to ccg4dal@gmail.com Do not forget to leave comments about the application. Thus, you will motivate me to further develop the application. Also, do not hesitate to ask me any questions you may have. NOTE: To be able to use the generated classes in your project, don't forget to download and reference the Required_Files. -

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. -

Dapper
A simple object mapper for .Net
Dapper is an open-source object-relational mapping (ORM) library for .NET and .NET Core applications. The library allows developers quickly and easily access data from databases without the need to write tedious code. Dapper allows you to execute raw SQL queries, map the results to objects, and execute stored procedures, among other things. It is available as a NuGet package. Dapper is lightweight and fast, making it an ideal choice for applications that require low latency and high performance. It is a simple yet powerful object mapping tool for any .NET language, such as C#, that enables developers to quickly and easily map query results from ADO.NET data readers to instances of business objects. It has excellent support for both asynchronous and synchronous database queries and batching multiple queries together into a single call. -

EF Core
Object-database mapper for .NET
EF Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations. Entity Framework Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations. EF Core works with many databases, including SQL Database (on-premises and Azure), SQLite, MySQL, PostgreSQL, and Azure Cosmos DB. To install EF Core, you install the package for the EF Core database provider(s) you want to target. This tutorial uses SQLite because it runs on all platforms that .NET Core supports. This application intentionally keeps things simple for clarity. Connection strings should not be stored in the code for production applications. You may also want to split each C# class into its own file. Query and manage relational data in a .NET Core app with an Object-Relational Mapper (O/RM). -

Entity Framework Analyzer
Analyze an Entity Framework edmx file to identity mapping issues.
This app will read an Entity Framework edmx file (currently tested with V5 of EF) and show all of the stored procedures, the conceptual functions, and the mappings between the two. If there are any procedures or functions that are not mapped, those will be listed as well. This tool was built to identify mapping issues when using Entity Framework with existing stored procedures. -

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.
