Is there a tool out there for visualizing dynamic call graphs? I saw a reference to one for Visual Basic 6 but I’d like one for .NET.
If I had to build a visualizer myself should I bother with the .NET profiling API or should I do something with Mono.Cecil? I started writing a CLI runtime with Cecil, but I guess it’d be easier if I just injected call-graph recording calls in the assemblies, although since I don’t know the execution route ahead of time and would have to instrument everything.
Profiling CLR is the purpose of the .NET Profiling API, so it seems to be perfect for your need. Most part of profiler products are based on top of it. But you’ll have to write unmanaged code, urk.
Using Cecil is possible too, and pretty straightforward if you just want to record enter/exit of methods.
EDIT:
Well, PostSharp is probably the best solution, as it allows you to handle such a requirement by relying on static weaving. AOP provides a better level of abstraction than directly rewrite IL with Cecil.
