## What it is
ABP Framework is an open-source, opinionated application framework for building enterprise web applications on .NET and ASP.NET Core. It provides infrastructure, startup templates, pre-built modules, UI themes, and tooling following domain-driven design and modular architecture practices.

## Use cases
- build enterprise web applications with asp.net core
- create multi-tenant saas applications in .net
- bootstrap a layered or modular monolith solution
- add identity, audit logging, and cms modules to a dotnet app
- build microservices with an api gateway in .net
- generate crud pages for a blazor or angular frontend
- apply domain-driven design in a c# project

## When to choose
- you want an opinionated, batteries-included architecture on ASP.NET Core
- you need built-in multi-tenancy, identity, and SaaS features
- you prefer DDD-based modular monolith or microservice templates
- you want pre-built application modules and UI themes to speed up delivery

## When to avoid
- you want a lightweight, unopinionated minimal API setup
- your team dislikes framework conventions and abstractions
- you need a stack outside the .NET ecosystem
- you require fully permissive licensing (LGPL-3.0 core, commercial tiers for pro tooling)
