AOP in .NET

Chapter 7. AOP implementation types

This chapter covers

• How runtime weaving works
• The difference between proxy and dynamic proxy
• Defining a postcompiler
• What postcompiled code looks like
• The trade-offs between runtime and compile-time weaving

After reading this chapter, you might still not be able to implement your own AOP tool, but you should have a basic understanding of how the two main types of AOP tools work. These two main tools, which I’ve been using in this book, are PostSharp and Castle DynamicProxy.

PostSharp is a postcompiler that performs weaving at compile time; Castle DynamicProxy generates proxy classes at runtime. I’ve glossed over some of the details of how these tools work in favor of how to use them. But the more ...
