It’s incredible the content renders to 140 pages, and it does not even include the class reference, which is still only available online or for download as a CHM.
But there’s an issue: although it looks like a book, it has been designed as a reference document and is not the best introduction to PostSharp. Online tutorials are still the preferred way to get started, and they are not included in the PDF.
Happy PostSharping!
