Signum Framework

Join the chat at

Signum Framework is an Open Source framework from Signum Software for writing data-centric applications over the latest technologies from Microsoft (.Net Core 2.1, C# 7.3, ASP.Net Web.API and Typescript 3.0) and web standard libraries (React, Bootstrap and D3) .

The main focus of the framework is being able to write vertical modules (database tables, entities, logic and React UI components) that can be shared between projects.

It provides a consistent model for N-layer architectures by moving the entities to the very center of your solution using Signum.Entities.

Our cutting-edge ORM, Signum.Engine, has a full LINQ Providers that avoids N + 1 problem and lets you UPDATE / DELETE / INSERT entities without having to retrieve them first.

Signum.React let's you write a Single-Page-Application using React, Bootstrap and TypeScript.

Main Features

  • Designed for vertical modules (aka: Bounded Context)
  • Entities-first approach
  • ORM with a full LINQ Provider
  • Unified validation
  • Schema generation and synchronization
  • WPF smart-client interface
  • React/Typescript SPA


  • Promote simple and clean code, avoiding astronautical architectures.
  • Favor compile-time checked code over dynamic code.
  • Create a solid foundation for the integration of application modules (on schema, BL and UI code).
  • Encourage a more functional way of programming.
  • Avoid code duplication.
  • Be a good citizen wherever we are (.Net, LINQ, React) following common practices and conventions.
