No Source Available

Question

I'm pulling my hair out trying to get framework source stepping working. Can someone please help?

I have:

- Visual Studio 2010

- Windows 7 x64

- disabled "Just My Code"

- enabled ".NET Framework source stepping"

- enabled "source server support"

- checked "Microsoft Symbol Servers"

- emptied my symbol cache

- rebuilt my project (a simple console app)

 

I get the following in the output window:

 

'Foo.vshost.exe' (Managed (v4.0.30319)): Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_32\mscorlib\v4.0_4.0.0.0__b77a5c561934e089\mscorlib.dll', Symbols loaded.

 

I get the following in the "Symbol Load Information":

 

C:\Windows\Microsoft.Net\assembly\GAC_32\mscorlib\v4.0_4.0.0.0__b77a5c561934e089\mscorlib.pdb: Cannot find or open the PDB file.
C:\vs10\Common7\IDE\mscorlib.pdb: Cannot find or open the PDB file.
C:\vs\dbg\symbols\MicrosoftPublicSymbols\mscorlib.pdb\A21F40D38EAB4B64B449E50DE8F5A3431\mscorlib.pdb: Symbols loaded.

 

I downloaded the debugging tools and ran srctool.exe:

 

>srctool.exe C:\vs\dbg\symbols\MicrosoftPublicSymbols\mscorlib.pdb\A21F40D38EAB4B64B449E50DE8F5A3431\mscorlib.pdb
C:\vs\dbg\symbols\MicrosoftPublicSymbols\mscorlib.pdb\A21F40D38EAB4B64B449E50DE8F5A3431\mscorlib.pdb is not source indexed

 

When I debug, I get the following in fiddler:

When i double-click a framework stack frame in the callstack I get the dreaded "No Source Available" page.

 

Please can someone tell me the magic incantation I have to perform in order to get this to work?
