Unable to find module 'mscorwks.dll'

Question

I try to use the winDBG to debug a dump file. When I run .loadby sos mscorwks.dll

It gave me an error message. Unable to find module \'mscorwks.dll\'

Has anyone

Answer 1

I had this issue as well and it turned out to be because the debugger was breaking into the app before the CLR was loaded. I had to let the app run throug further before I could do much of anything.

Doing this in windbg might help:

sxe ld:mscorlib
g
(... breaks again ...)
.loadby sos mscorwks

The 'sxe ld:..' stops on module load.

As Sixto mentions, if you are debugging dotnet 4 apps you'll need to replace the last line with

.loadby sos clr
