VS 2010: Max line length guide does not render

Question

In VS 2008, we were able to add a max line length guide ref: http://blog.feradz.com/2009/02/add-line-length-marker-in-visual-studio/

However when we attempt to do the same thing in VS 2010, it does not work. Does anyone know how to achieve this in VS 2010?

Answer 1

The guidelines are not supported in VS 2010 natively (I Assume as part of the WPF rewrite of the editor this hidden functionality was not maintained).

But you can add them back with an extension (or at least in the beta/RC you could): Editor Guidelines UI – Extension #4 .

Update: I now have this working in Ultimate Edition RTM, by adding the extension from Tools | Extensions and searching online for "text guideline".
