Unfortunately, Visual Studio does not support indentation lines out of the box.

Andrew Hare
Thanks for your reply. Are there any third party plug-ins that add this functionality?

These lines are arguably more useful in Python where indentation denotes nesting. In C#, nesting is explicitly marked by curly braces. I feel as though curly braces provide the visual cues I need to see this kind of thing, so you might just try to persevere -- in time the cognitive load associated with glimpses of C# versus glimpses of Python will reach equilibrium.

VS2010 implements the text editor in WPF and there are some examples online of creating plug-ins that augment the text editor area. This could be a fun project without being too difficult.

I am envious of Python's indentation-centric nesting. I wish that the C# compiler supported something like that. I wish that white space was part of the language. It would make tooling support for the language better as well.

Drew, your assessment seems spot on. However, for some reason, the curly braces throw me off. I feel like I'm constantly trying to figure out where a block of code starts and ends. This could be because I'm relatively new to programming in general. I definitely feel like Python's use of whitespace and indentation makes it much easier to read in comparison to C#'s curly braces.

I've seen it called structural highlighting or code outlining.

There's a Visual Studio plug-in called CodeRush from Developer Express that supports this (bottom of the page) and a lot more.

update:

As divo mentioned, there is a free lite version of CodeRush. I confirmed that it includes structural highlighting.

Please note that there is a free edition for C# (and maybe VB, haven't checked it) available at http://msdn.microsoft.com/en-us/vcsharp/dd218053.aspx
