PostSharp 

The implementation assemblies of Metalama.Framework for Roslyn 4.8.0. This package should normally never be referenced in any user project.

Automatically generates Equals and GetHashCode for annotated classes.

A class annotated with [DeepSerializable] and all of its fields, recursively, are marked as serializable.

An example PostSharp add-in that adds Console.WriteLine("Hello World!") to every method annotated with [HelloWorld].

Throws an exception if your unsafe code attempts to write to memory you don't control

Allows you to make all or almost all of your methods virtual.
