Signum Framework is an Open Source framework from Signum Software for writing data-centric applications over the latest technologies from Microsoft (.Net Core 3.1, C# 8.0, ASP.Net Web.API and Typescript 3.7) and web standard libraries (React, Bootstrap and D3). It uses either Microsoft SQL Server or PostgreSQL to store data.

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 you write a Single Page Application using React, Bootstrap and TypeScript.

• 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.

• Signum Framework: Know what makes Signum Framework suited for building complex business applications.
• Signum Extensions: A set of ready-to-use modules that work with any Signum Framework application.
• Documentation: Documentation (from Markdown files in GitHub)
• Tutorials: Tutorials (in docx and pptx)
• Create Application: The simplest way to get started. Create a new project by renaming and customizing Southwind example application.

Signum Framework doesn't use any numeric versioning, since is distributed as source code we just use Git commit hashes.
