Писал сложную форму на Silverlight и когда дописал, с ужасом обнаружил, что у меня где-то происходит утечка памяти. Волноваться я не стал, а снял несколько дампов на 3,5 гигабайта и хотел было в WinDbg выяснить в чём собственно дело, но SOS упорно посылал меня на любую из команд.
Дело в том, что Silverlight это x86, поэтому, как только мы загрузим дамп в WinDbg x86, то надо явно сказать, что работать мы будем 32х битном режиме.
Волшебное слово:
!wow64exts.sw
Пример:
.loadby sos coreclr
.chain
!wow64exts.sw
Дальше работаем как обычно.
Have fun
