PostSharp

PostSharp is a mature aspect-oriented programming (AOP) and code weaving framework for .NET. It automatically injects repetitive infrastructure code during the build process, helping you eliminate boilerplate while keeping your business logic clean and maintainable.

Features

• Aspect-oriented programming (AOP) using attributes
• Build-time code weaving (MSIL rewriting)
• Eliminate repetitive boilerplate code
• Built-in aspects for logging, caching, threading, and MVVM
• Automatic INotifyPropertyChanged implementation
• Custom aspect development framework
• Architecture validation and coding rule enforcement
• Full support for asynchronous code
• Works with .NET Framework and modern .NET projects
• Mature ecosystem with over 20 years of development

Why PostSharp?

• Reduce repetitive infrastructure code
• Improve readability by separating cross-cutting concerns
• Enforce architectural rules across large codebases
• Increase developer productivity while reducing maintenance costs

PostSharp is ideal for teams building large .NET applications that want to automate common implementation patterns such as logging, caching, validation, thread safety, and property change notifications without cluttering business code.
