I have been getting a stackoverflow exception in my program which may be originating from a thirdparty libary, microsoft.sharepoint.client.runtime.dll.
Using adplus to create the crash dump, I'm facing the problem that I'm struggling to get any information from it when i open it in windbg. This is what I get as a response:
> 0:000> .restart /f

Any ideas as to how i can get more information from the dump, or how to use it to find where my stackoverflow error is occuring?
The problem you are facing is that the process is 32-bit, but you are running on 64-bit, therefore your dump is a 64-bit dump. To make use of the dump you have to run the following commands:
.load wow64exts
.effmach x86
!analyze -v
The last command should give you a meaningful stack trace.
This page provides lots of useful information and method to analyze the problem. http://www.dumpanalysis.org/blog/index.php/2007/09/11/crash-dump-analysis-patterns-part-26/
You didn't mention if your code is managed or unmanaged. Assuming it is unmanaged. In debugger:
.symfix
.reload

Look through the call stack for all threads and identify thread that caused SO. It is easy to identify the thread with SO, because the call stack will be extra long. Switch to that thread using command ~<N>s, where is thread number, dump more of the call stack using command k 200 to dump up to 200 lines of call stack. At the very bottom of the call stack you should be able to see the code that originated the nested loop.
If your code is managed, use SOS extension to dump call stacks.
