Cannot use WinDbg and SOS in Visual Studio Immediate window

Question

I'm following this tutorial: link. At step 8, when I say .load sos in the Immediate Window, it just pukes expected expression.

System: Win 7 x64, Visual Studio 2012 Premium. I have an installed Debugging Tools for Windows (x64) 11/14/2012, Now I installed X64 Debuggers And Tools. I have Windows SDK for Windows 7 (7.1). WinDbg.exe is in c:\Program Files\Debugging Tools for Windows (x64)\ and I can start it from start menu. However I cannot find sos.dll, which supposed to come with the Debugging Tools for Windows (x64).

How can I make this happen?

Bonus question: {,,kernel32}_LoadLibraryExW@12 in Step 4 doesn't work, I use {,,kernel32}LoadLibraryExW, but then I cannot figure out where is the loaded dll name. I was poking around with the registers.

Answer 1

NTSD command support (MSDN) and Immediate Window Commands describe which WinDbg commands (or similar to WinDbg) are supported by Visual Studio 2005, 2008 and 2010. It's only a small subset:

.S
.X
.K
.U
.~
.Reload
.Sympath
.Cxr
.Exr
.Load
.Unload
.Unloadall

Most important is probably the .Load which allows loading extensions and then using ! commands of the extension.

It seems that support for WinDbg commands was dropped with VS 2012, since you cannot call the web page for VS versions higher than VS 2010.
