Entity Developer is a powerful ORM designer for ADO.NET Entity Framework, Entity Framework Core, Hibernate, LinqConnect, Telerik Data Access, and LINQ to SQL. It introduces new approaches for designing ORM models, boosts productivity, and facilitates the development of database applications.

Develop Faster
Design your data access layer visually, via drag-n-drop, and then generate code automatically. Or simply generate a model from a database or vice versa in a couple of minutes.

Do Less Mistakes
Automating data access layer generation helps you do less mistakes in your code. Our code generation templates are used for years and utilized by hundreds of users.

Professional Tool
Devart develops solutions for .NET Data access for 15 years, and our ORM designer is 9 years on the market. It is a professional tool, created by experienced developers and designed to make you more productive.

Configure generation with lots of various options
Flexibly configure naming of generated classes, members, and methods
Get from database to ready-to-use code in minutes

Model-First Approach Support
Create a model and then generate a database from it automatically. Apply model changes to the database without losing data where possible.

Generate a database from a model in a few clicks
Specify a default set of properties to be added to each new entity
View, select, and apply model changes to the database
Flexibly configure naming of generated tables and columns

Visual Studio Integration
Entity Developer is seamlessly integrated into Visual Studio; however, if you don't have Visual Studio, you still can use Entity Developer as a separate application.

Design model directly in the IDE
Visual Studio 2008 - 2019 support
Refactoring integration
Code is generated when you save the model
Errors in model are displayed in Visual Studio Error List
Model diagrams, template editor behave like usual IDE documents
Documentation is integrated into Visual Studio documentation

Powerful Refactoring
Powerful Model Refactoring wizard allows you to quickly configure mapping aspects that cannot be automatically generated from database. It allows you to create:

inheritance hierarchies,
complex types,
table splitting
in just a couple of clicks.

Optimized Work with Large Models
Entity Developer is optimized to ensure comfortable and efficient work with large models, containing thousands of entities.

Highly optimized metadata retrieving
Split model into several thematic diagrams
Fast code generation

LINQ Query Execution against Models
Execute LINQ, Entity SQL, or HQL queries (depending on the ORM used) without the need to finish your application.

Test your model at design-time
Preview the returned data and browse related entities
View and edit data of the database tables directly

Template-Based Code Generation
Template-based code generation system in Entity Developer can satisfy even the most demanding developers.

Generate C# or Visual Basic code
T4-template based code generation
Editable templates

Wide Choice of Predefined Templates

Generate all classes to one file or file per class
Configure project folders to output files
Generate extensible partial classes with code behind
