intro to Code Access Security slides
Neat, the slides from my “Introduction to Code Access Security” presentation are available on the New Jersey Microsoft Developer's Group site. The presentation was a 30 min, high-level introduction to Code Access Security. Very newbie-friendly :)
While you are there, be sure to check out Brad (Infragistics) McCabe's ASP.NET tips and the excellent WinForms binding presentation by Jeff Lyttle.
