CoSOS (cousin of SOS) is an open source extension for WinDbg focusing on .NET memory fragmentation (!gcview
) and threading issues (!wfo
, !tn
).
Typically, the extension is not available side by side to any other DLL, so it is usually loaded with .load x:\full\path\to\cosos.dll
. It requires that SOS is loaded and currently works with 32 bit applications only.
