PropertyChanged.Fody is a Fody add-in that injects INotifyPropertyChanged notification code into property setters at compile time via IL weaving. It eliminates boilerplate in C# MVVM applications by automatically raising PropertyChanged events, including for dependent computed properties.

Use cases

• remove inotifypropertychanged boilerplate from c# viewmodels
• automatically raise property changed events at compile time
• notify dependent computed properties when source properties change
• simplify mvvm viewmodel property change notifications
• weave property change code into existing c# classes

When to choose

• you write WPF, UWP, or other .NET MVVM apps and want zero-boilerplate change notification
• you want dependent properties to automatically raise change events
• you prefer compile-time weaving over runtime reflection or base-class approaches

When to avoid

• your project does not use the .NET/C# ecosystem
• you need runtime-configurable notification behavior rather than compile-time injection
• you are unwilling to adopt the Fody build pipeline or its patron licensing model
