debugging - Current possibilities for tracing program flow in C#?

Question

I have used Postsharp a few years ago to trace program flow during execution without needing to manually add trace statements to the methods.

Is there any other new ways to trace execution to to debug output in a similar way?

(Preferably a way that doesn't need to instrument the built assemblies. Maybe not possible?)

Answer 1

If you only want this ability at debug time, there's Microsoft IntelliTrace that's a part of Visual Studio 2010 Ultimate, and there's Sergey Vlasov's RunTime Flow. The former makes your program run very slow. Haven't tried the latter.
