AGENDA
- What's Fody?
- What can be done?
- Show me the code!
- Our own example!

FODY?
Extensible tool for weaving .net assemblies.
Weaving??
Manipulating:
- source code - compile-time
- T4, WebForms designer
- IL instructions - compile-time
- Fody, PostSharp
- JIT code - run time

IL Manipulation Pros
- reduces source code clutter
IL Manipulation Cons
- harder to maintain/grasp
FODY
- solutions for 'pluming-code' tasks
- INPC, Logging, Auditing etc.
- remedy for IL manipulation cons
- easier to maintain/grasp
- available as nuget
- *.Fody
- source code on github (https://github.com/Fody/Fody)
- MIT license
The plumbing tasks Fody handles
- Injection of the MSBuild task into the build pipeline
- Resolving the location of the assembly and pdb
- Abstracts the complexities of logging to MSBuild
- Reads the assembly and pdb into the Mono.Cecil object model
- Re-applying the strong name if necessary
- Saving the assembly and pdb
