SOSEX is one of the few existing Windows Debugger extensions for managed code (.NET). It adds a few useful commands to the basic SOS, but its command reference is not easy to find online.
The list of its commands is available via
!sosex.help command. You might find the resulting list useful when considering this extension for your debugging scenario:
