Debugging Mixed mode (C# , C++) application

Question

I am debugging an issue with a mixed mode (managed and unmanaged) application.

The actual issue is within the unmanaged code.

I have loaded SOS dll into Windebugger. But is shows me the call stack only upto managed mode since i have loaded SOS dll. How do I see the call stack of unmanaged code as well?

The SOS command !dumpstack will produce a complete stack trace with managed and unmanaged code. Since it's an issue in unmanaged code, the usual debugger stack trace commands (k and variants) may also be useful.

!sosex.mk will give a complete stack trace in a way that is easy to read.

it says IXCLRDataStackWalk::Next failed. Error = 0x80004002 – Rockstart Dec 21 '12 at 11:35
Is this a full memory dump? What does !sos.clrstack say? – Steve Johnson Dec 22 '12 at 08:22
Yes it is full memory dump. clrstack shows callstack only upto managed code. – Rockstart Dec 22 '12 at 10:50
