Software Diagnostics Library

Recently when looking at one of process memory dumps with CLR runtime I got this message when trying to load SOS extension from the appropriate Framework location:

0:022> .load [..]\Microsoft.NET\Framework\v2.0.50727\sos.dll
------------------------------------------------------------
sos.dll needs a full memory dump for complete functionality.
You can create one with .dump /ma <filename>
------------------------------------------------------------

So I literally did what was asked by saving a new dump from the dump:

0:022> .dump /ma c:\userdumps\dump-as-asked.dmp
Creating c:\userdumps\dump-as-asked.dmp - mini user dump
Dump successfully written

I got a slightly bigger dump than the original and after that SOS didn’t complain when I opened the new dump and loaded the extension.
