## What it is
ASP.NET Boilerplate (ABP) is an open-source application framework for building modern web applications on ASP.NET Core and EF Core, with built-in Domain-Driven Design layering, multi-tenancy, and convention-based best practices. Official support ends in May 2026, with ABP Framework recommended as the successor.

## Use cases
- build a multi-tenant SaaS web app in ASP.NET Core
- start a layered DDD web application with best practices
- structure an n-layer .NET application with repositories and app services
- add multi-tenancy from database to UI in a .NET project
- bootstrap an admin web application with Angular or MVC frontend
- enforce SOLID architecture conventions across a .NET codebase

## When to choose
- you are maintaining or extending an existing ASP.NET Boilerplate codebase
- you need a proven DDD-based .NET framework with integrated multi-tenancy and extensive documentation
- you want a mature, MIT-licensed framework with startup templates for ASP.NET Core or MVC 5.x

## When to avoid
- you are starting a brand-new project, since support ends in May 2026 and ABP Framework is the recommended successor
- you want a lightweight micro-framework rather than an opinionated full-stack architecture
- you need long-term community support or frequent updates beyond the end-of-life date
