CSLA .NET is a software development framework for building a reusable, maintainable object-oriented business logic layer in .NET applications. It supports 1-, 2-, and n-tier architectures with mobile objects, running across Windows, web, service, and mobile platforms including Blazor, MAUI, WPF, and WinForms.

Use cases

• build a reusable business logic layer for .NET apps
• share business objects between server and client in an n-tier architecture
• create maintainable object-oriented domain models in C#
• build line-of-business apps with Blazor or MAUI
• abstract data persistence behind business objects
• separate business rules from UI across desktop and web frontends

When to choose

• you want a proven, long-established framework for object-oriented business layers in .NET
• your app spans multiple UIs (web, desktop, mobile) sharing the same business logic
• you need flexible n-tier deployment with mobile objects
• you want business objects with built-in validation, authorization, and persistence support

When to avoid

• you prefer lightweight micro-ORM or DDD-style hand-rolled domain models
• you work outside the .NET ecosystem
• you want a minimal framework without its conventions and base classes
• your team is unwilling to learn CSLA's object model and patterns
