2. you are now supposed to be woken up!

3. however, you should already know that!

4. The Big Picture Plug-Ins PostSharp Core PostSharp Laos Hosts MSBuild Host Command-Line Host Runtime Host

5. A finer picture PostSharp Core Code Object Model represents a .NET module Module Reader reads a .NET binary assembly into the Code Object Model Module Writer writes the Code Object Model into a binary assembly (using ILASM) Code Weaver provides the infrastructure for MSIL injection Platform Infrastructure executes projects, loads plug-ins, loads and schedules tasks Plug-in performs specific analysis or transformation Host bootstraps PostSharp and invoke project executions Independent Program uses PostSharp without the Platform Infrastructure PostSharp Laos PostSharp4EntLib PostSharp.Samples.Trace custom plug-ins command-line utility MSBuild task PostSharp.Samples.Host custom application servers PostSharp.Samples.Explorer

6. Core vs. Laos PostSharp Core PostSharp Laos Objective Absolutely free editing of .NET assemblies Aspect-Oriented Programming Easily Primitives Low-Level (MSIL) High-Level Audience ISV, MSIL/PostSharp specialist Everyone Learning Curve Steep High Complexity / Error Proneness High Low Runtime performance Fast Slower Licensing of extensions GPL/Commercial Any
