This distribution should remove much of the mystery about how PostSharp integrates in the build process. Actually, since the installer does not modify the MSBuild target files for you, you have to do it yourself. The interesting thing is that you can do it in a per-project basis: instead of modifying global MSBuild target files, you can just import PostSharp in the projects that actually need it.
If you think this kind of installation is for you, download the 'Binary - No Installer' package, and read carefully the installation instructions in the file doc/Build-Instructions.
Since this kind of distribution is quite new, I am looking forward for
your comments.
Happy PostSharping!
