AGENDA


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

About.me


Reflection: 1492

Mono.Cecil: 1493

Solution?





Fody (ptak) -> wikłacze -> weaver -> IL weaver -> Fody (tool)

FODY?



Extensible tool for weaving .net assemblies.

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

Weaving??

Manipulating:

  • source code
  • IL instructions
  • JIT code
