WinDbg: SOSEX Help – Command Reference

SOSEX je jedno z mála rozšíření Windows Debuggeru pro .NET (managed code). Přidává pár užitečných příkazů k základnímu SOS, není však snadné seznam podporovaných příkazů online najít.
Seznam příkazů se dá získat přes !sosex.help. Výstup se může hodit, pokud hledáte, která extension bude pro váš scénář diagnostiky nejpříhodnější.
