In Visual Studio is there an automatic way to search over file(s) and find all classes/properties/methods that aren't referenced. Essentially abandoned code.
I don't want to manually have to right click on each and select "Find All References"

I don't believe there is. – Mitch Wheat Jul 25 '13 at 10:42

Resharper offers this IIRC. – leppie Jul 25 '13 at 10:45

So nothing out of the box. Could I write a script to do it via VS? – aherrick Jul 25 '13 at 10:47

@aherrick You could probably use [Roslyn](http://msdn.microsoft.com/en-us/vstudio/roslyn.aspx). – Cédric Bignon Jul 25 '13 at 10:55

This is not a feature of Visual Studio in the current version. Using Roslyn you could code and Inspector yourself, but Roslyn doesn't offer one out of the box either at the moment. The walk-through on Semantic analysis should get you started. The roslyn forum is a good place to seek help or find examples, and there's a well monitored tag on StackOverflow as well of course.
Productivity plugins like Resharper and Code Rush offer this for sure. There are other similar tools that might have this feature JustCode, VisualAssist, CodeItRight are likely candidates.
You can also use something like Visual NDepend to detect unused methods. Their new command Linq to Code features should make it relatively easy to build a commandline tool that fishes out all unused calls.

Hmm I'd hate to have to reinvent the wheel here. This has to have been done already. Strange it isn't built into VS seems like a huge win. – aherrick Jul 26 '13 at 08:19

A bit late but if you install SSDT (Sql Server Data Tools) this also add grayed reference count to each method in visual studio. Note: This is actually "code lens" which is no longer available for VS2015. Installing the SSDT is the way you can have "code lens" in VS2015.
