Download dump file; VS does not find my source code

Question

I am developing a .NET 4.0 application in VS 2010.

I am trying to use dump files for the first time, but when loading minidump in VS, I cannot debug it, since VS cannot find the source files.

Here is what I did:

• In Options -> Debugging -> Symbols I added an app build dir file that contains pdbs.
• Run the application in the VS debugger. Selected Debug -> Break All .
• Selected Debug -> Save dump as
• I went to the dump file in Windows Explorer and opened it. This opened up a new instance of VS.
• I clicked "Debug with mixed." This opened a new tab that said "There is no source code available for the current location .

I tried to understand why VS did not load my pdbs:

• Open Debug -> Windows -> Modules
• The Symbol Status column for MyApp.exe said "Symbols loaded."
• For MyApp.vshost.exe, he said: "Cannot find or find the PDB file."
• Right-click on MyApp.exe, select "Symbol Download Information". He said: "MyApp.pdb: characters loaded."
• The same goes for MyApp.vshost.exe. He said vshost32.pdb: cannot find or open the PDB file. (note that for some reason it is looking for a file named vshost32.pdb, not MyApp.vshost.pdb)

So any ideas?

Answer 1

Solved a problem. VS looked at the lowest method in the call stack, which was a system method somewhere in ntdll.dll. Therefore, naturally, there was no source for this. I had to click on my own method in the Call Stack window to go to my own code for which the source was available.
