As you see,I use VS2010 Professional to load sos.dll ，but other commands can't be used and continues throw an Exception,like this:

.load sos.dll extension C:\Windows\Microsoft.NET\Framework\v4.0.30319\sos.dll loaded

!clrstack PDB symbol for clr.dll not loaded OS Thread Id: 0x6d4 (1748) Child SP IP Call Site 0028f2b8 00370094 ConsoleApplication1.Program.Main(System.String[])Error during command: IDebugClient asked for unimplemented interface

0028f528 699e21bb [GCFrame: 0028f528]

My pc runs on 64Bit Win7 ,can that be the problerm?

Can anyone help me?Really appreciated!

  • If you believe this is a 64-bit related issue, you may try explicitly loading the 64-bit sos.dll `.load C:\Windows\Microsoft.NET\Framework64\v4.0.30319\SOS.dll` – Sean Cline Nov 27 '12 at 02:45

Have you enabled "Unmanaged code debugging"?

See this link:

Did you upgrade to .NET 4.5? It appears that can cause issues.

Unable to launch SOS.dll using VS 2010

I know in WinDBG you can issue this command:

.loadby sos clr

This causes it to load the sos.dll that is in the same directory as the clr.

  • Thank you.No,I didn't. And use ".loadby sos clr " command Windbg throw an Exception:Unable to find module 'clr'... Then i use the absolute path ,it gives me any response – Lyon Gu Nov 27 '12 at 03:10
  • What does ".loadby sos mscorwks" give you? What version of the framework are you targeting? – taylorjonl Nov 27 '12 at 03:24
  • >Unable to find module 'mscorwks'
    .Net 4.0 Now I'm debugging in my 32bit VM,sos gives me that:PARAMETERS: args (0x0012f3d8) = 0x00c8c450 LOCALS: 0x0012f3d4 = 0x00000000,but in the main function ,there's a console.writeline() statement,as if it didn't execute... I really should say:you're such a nice guy!     – Lyon Gu Nov 27 '12 at 07:13
  • If ".loadby sos clr" says it can't find CLR it may be too early in the process, and the CLR isn't loaded yet. Try running this command before anything "sxe ld:mscorlib", that should cause it to break when the CLR is loaded, then do the ".loadby sos clr" command, see what happens. – taylorjonl Nov 27 '12 at 17:13
  • Thanks,really appreciated!But I really can't follow you... I'm a rookie,I just want to use SOS.dll now.Windbg is a bit difficulty for me now... And the reason of the error, i don't konw either.But the reason why the local is 0x00000000 is I didn't set any **breakpoint** and execute directly which i didn't know before.So sorry for **wasting your valuable time**! – Lyon Gu Nov 28 '12 at 05:44
