This one is really getting me down. I can't find any info on this on the web and urgently need to solve it. The debugger was working well up to resently so its either a config issue, dependancy issue or a compiler issue but I can't see where.  Can anyone give me a heads up

Hi,

please check if you are trying to run a release build with the debugger attached. This is not supported.

I cannot think of any other situation where this could happen.

regards,

Siegfried

Siegfried,

thanks for the fast responce. I've checked the project settings and recompiled again with the same result.

Any other possible casues of the above exception?  Could a reference dll be causing it? I've also tried turning of the JIT debugging but no success yet.

Talk soon

The last log message before the exception is "12:22:09.241 [1] DEBUG - Debugger: Callback: LoadModule C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files oot\fb599c57\910982b\assembly\dl3\6b89222e\b02ee946_3022ca01\Gios Pdf.NET.DLL"

My best guess it that the debugger found the "Pdf.NET.pdb" symbol file and therefore tried to load the dll as if were a debug-build dll (release-build would not have a pdb symbol file).  Unfortunately the dll was acutally release-build and thus it failed.  I have tried it - debug-build dll loads fine even if the main application is release-build, but release-build dll with existing pdb file throws this exception.

To fix it, try deleteing the file "Pdf.NET.pdb".

Thanks very much, that makes sense. It was the last project I compiled when working on this job two weeks ago. I must have compiled a release version, don't know why though as this is still only a alpha/ test version and I was actually debugging that project. Still I was in a rush and as you probably know you some times do silly things when your stressed.

I've removed the pdb file and all is good. Thanks a million.

P.S I hope this thread helps others in a similar bind, as the other threads here with similar issues did not have a resolution

As of r5265 this should work without the workaround.

Thanks, that helped me too.

I was thinking maybe the problem is that IIS is running as 64 bit proc, and my web server cassini is running 32 bit, and then my app is compiled as any cpu.   heck, i really got mixed. Now it works fine.

Thanks!
