I'm using a 3rd party tool, which uses a 4th party plugin. Occasionally, the tool will hang when launched. Looking at the stack traces, I can see a few threads are waiting on WaitForSingleObject, and my bet is that they're blocking each other. Some of the threads start at the 3rt party tool, and some at the 4th party plugin. What I'd li...

Running a (seg)faulty native windows binary from within a cygwin shell leads to restart the binary for several times. Since I want to analyze the bug I activated windbg as the post mortem debugger (yes, as administrator), but somehow cygwin interferes and windbg does not get triggered. OS: 64bit Windows7 (happened on WindowsXP as well)...
Hi, I know this was answered before, but I'd like to pose a somewhat different question. Is there any conceivable way to implement GC.GetAliveInstancesOf(), that can be evaluated in Visual Studio Debug Watch window? Sasha Goldstein shows one solution in this article, but it requires every class you want to query inherit from a specific...

Is there any microsoft or even non-official documentation for SOS for Silverlight. Other than a few web posts I have seen zero documentation for it on MSDN.

I'm a complete WinDbg newbie and I've been trying to debug a WindowsXP problem that a customer has sent me where our software and some third party software prevent windows from logging off.

I'm embarrassed to post this but it's been awhile since I worked in C++, been with C# for awhile. I'm converting old (not written by me) vs2003 and 05 C++ code to vs 08. In addition to lots of lumps during conversion, I want to add debug logging so I can monitor what is going on when I attach with windbg. I've searched the archives here ...

I would like to dump the fields and offsets of structures in the same way as windbg's dt command. Let's say for example I would like to dump the _PEB structure which is in the Microsoft Public symbols (since windbg's DT command works).
