Visual Studio "document outline" for C# file

Question

In Visual Studio (2013/2015/2017), the Document Outline window for C# files is always empty ("There are no items to show for the selected document."). It seems that this functionality is not (not yet / no more) implemented.

But then, how do I view the structure of the file? Is there any extension which implements this functionality?

• showing only the selected/opened file
• show regions
• move/rename members
• show documentation

Using the Solution Explorer and Class View are NOT the solution. In the old Visual Studio 2003, I did use a self written Add-In, because it was easy to read the structure. (There were also other tools but I cannot find them anymore). So I ask here which solution you know. :-)

Answer 1

There is also CodeMaid which provides the same functionality as JetBrains Resharper, but is free.

Answer 2

It helps you look at the nested structure of certain types of files, e.g. windows forms designer file, open a form designer you should see all controls on the form shown in nested structure in the document outline window.
