How do I set a breakpoint on every access to a class

Question

When working with third party systems, especially very configurable systems that dynamically load providers, controllers, components and so on, I sometimes just want to know when a certain object or class is accessed. Normally, I'd place a breakpoint on any potential lines in my source (a nuisance, but it works), but if source is not available:

How can I instruct Visual Studio 2010 Ultimate to break on any and each access to a given class?

_{Note: as far as my experience goes, this is not generally possible, but I'd like to see it confirmed}

Answer 1

Not the most elegant, but if you Ctrl+F public then you can spam between F9 [set breakpoint] then F3 [find next] to set a breakpoint on every public entry point into the class.

You might also want to add breakpoints for protected and internal entry points, and any explicit interface implementations (declarations that don't have public)

Answer 2

You can click Debug > New Breakpoint > Breakpoint at Function. Ctrl-B brings you there directly. It'll allow you to break at a specific function.

During debugging, you can see in the Breakpoints-window whether the method is found and will be hit (red round icon) or not (white with circle icon, as of disabled breakpoint), just as with normal breakpoints.
