Trying to debug Windows Store App from dump files

by

ok, with the help of the Windbg Extension PDE.dll from Andrew Richards, I see that your application crashes because of an not handled System.UnauthorizedAccessException.

I used !PDE.dpx -dse to shows all Stowed Exceptions (those 0xC000027B exceptions):

0:006> !PDE.dpx -dse
Start memory scan  : 0x0551fc7c ($csp)
End memory scan    : 0x05520000 (User Stack Base)

0x0551fc94 : 0x012db914 :  !dse combase!STOWED_EXCEPTION_INFORMATION_V1
0x0551fcdc : 0x0163c168 :  !dse combase!STOWED_EXCEPTION_INFORMATION_V1

Now I use !PDE.dse to display its data:

0:006> !PDE.dse 0551fc94

Here you can see that the underlaying issue is the System.UnauthorizedAccessException. The dmp is only a minidump, so I can’t see what CryptoQuoteW8cs!UNKNOWN+0x81 does.

Use the Application.UnhandledException event to handle exception that you have not handled via try/catch to prevent the app from crashing.

Here is a good guide on how to handle exceptions:
