How AOP works with PostSharp

You add the PostSharp package to your project. Then, you annotate your code with attributes. The C# compiler builds your code into binary, and then PostSharp analyzes the binary and injects the implementation of aspects. Although binaries are modified with injected code at compile time, your project’s source code remains unaltered. This means you can keep your code nice, clean, and simple, which in turn makes maintenance, reuse, and extending existing code bases much easier in the long term.
