Here are two videos documenting the simple steps required to migrate your AutoCAD ObjectARX and .NET plug-ins to AutoCAD 2013. The videos were recorded for the benefit of our Autodesk Developer Network partners during the Beta cycle, which means you’ll see/hear references to AutoCAD ‘Jaws’. Jaws was the codename for AutoCAD 2013 during development, so just substitute ‘2013’ every time you see/hear the word ‘Jaws’.
Download the videos from the following links, extract the files from the zip, and click in the HTML or MP4 file to play the video.
ObjectARX Migration – recorded by Fenton Webb. (Includes an AutoCAD 2013 version of the Visual Teefy project migration wizard).

Update (May 29th 2012): See this post for a clarification of the use of extension methods in AutoCAD 2013.
