Hi All,
I'm using windbg version 6.3.9600 for some manage application experiments. Upon loading the SOS extension with the loadby command I get the following exception. The exception is presented upon the first use of any SOS command:
0:007> .loadby sos clr
0:007> !threads
c0000005 Exception in C:\Windows\Microsoft.NET\Framework\v4.0.30319\sos.threads debugger extension.
PC: 6fec7713 VA: 00000000 R/W: 0 Parameter: 00000000
0:007> !threads
ThreadCount: 5
UnstartedThread: 0
BackgroundThread: 2
PendingThread: 0
DeadThread: 2
Hosted Runtime: no
If I use the load command the exception is not presented. Can someone please explain why this is happening and a possible resolution.
