How to extract functions call graph from a visual basic file?

Question

I'm currently facing a large piece of legacy code which I have to understand and rewrite to make it more maintainable.

Is there a tool that would show let me explore easily the graph of the function calls in the file ?

Any text output like

Method1
    Method2
    Method3

Method2
    Method3

Or graphical like

could help a lot.

Answer 1

Resharper allows your to inspect incoming or outgoing calls to a method.

I don't know of a way to do this in visual studio without a plugin.

Also, NDepend might be an option for you as well. I've never used it, but it looks like it can do what you're requesting.

Answer 2

Maybe that is only in Ultimate edition. But you can download trial of it from Microsoft Servers.
