C# Call Graph Generation Tool

Question

I just got a heaping pile of (mostly undocumented) C# code and I'd like to visualize it's structure before I dive in and start refactoring. I've done this in the past (in other languages) with tools that generate call graphs.

Can you recommend a good tool for facilitating the discovery of structure in C#?

UPDATE

In addition to the tools mentioned here I've seen (through the tubes) people say that .NET Reflector and CLR Profiler have this functionality. Any experience with these?

Answer 1

I'm not sure if it will do it over just source code, but ANTS Profiler will produce a call graph for a running application (may be more useful anyway).

Answer 2

SequenceViz and DependencyStructureMatrix for Reflector might help you out: http://www.codeplex.com/reflectoraddins

Answer 3

Visual Studio 2010.

Plus, on a method-by-method basis - Reflector (Analyzer (Ctrl+R); "Depends On" and "Used By")

Answer 4

I've used doxygen to some success. It's a little confusing, but free and it works.

Answer 5

As of today (June 2017), the best tool in class is Resharper's Inspect feature. It allows you to find all incoming calls, outgoing calls, value origin/destination, etc.

The best part of ReSharper, compared to other tools mentioned above: it's less buggy.

Answer 6

It's bit late, but http://sequenceviz.codeplex.com/ is an awesome tool that shows the caller graph/Sequence diagram. The diagrams are generated by reverse engineering .NET Assemblies.

Answer 7

Concerning NDepend, it can produce some usable call graph like for example (image full size here)

Answer 8

NDepend is pretty good at this. Additionally Visual Studio 2008 Team System has a bunch of features that allow you to keep track of cyclomatic complexity but its much more basic than NDepend. (Run code analysis)
