I've never seen this in C# code! How common is this? Do you have any references? Sounds like a useful convention (it's nigh impossible to google). VS only distinguishes between `///` (docblock) and all other (double, quadruple,quintuple, /*/). But maybe there's an extension.
StyleCop is used for analyzing code style in C# code.
Specifically:
> If the comment is being used to comment out a line of code, begin the comment with four forward slashes rather than two.
StyleCop relies on this to tell the difference between commented code and code comments. If you use ReSharper, it can do some nifty transformation to strike these out in the IDE which is kinda cool too.
I’m a big fan of StyleCop to enforce consistent code styles. (Even if it’s not always what I may aesthetically prefer.)
