Can I see what is referencing an object while debugging?

Is it possible, while debugging a Silverlight app, to view all current references to an object?

I know that WPF developers have the ability to use the SOS.dll, but that cannot be loaded in the VS2008 IDE while debugging a Silverlight app. I've tried it, but the load command gives me the error:

.load C:\Program Files\Microsoft Silverlight\3.0.40818.0\sos.dll

SOS not available while Managed only debugging. To load SOS, enable unmanaged debugging in your project properties.

Un开发者_JAVA技巧fortunately, there is no way to enable unmanaged debugging for a Silverlight app through the VS2008 IDE. I've also tried to the 'Attach To' the process, but still, no dice.

I'm not sure if its possible from VS2008, but if you download and run WinDbg as part of the debugging tools for windows and you can attach on to a process hosting a silverlight plugin.

Once you attach you can run the following to use SOS:

.loadby sos coreclr

There are some examples out there for tracking down managed memory leaks, etc:
