crazy asp.net error - asp.net-mvc

Question

Hi I am having a problem debugging an issue on a website. Everything works locally, the local and server databases are the same
The strange thing about the error is that it points to my local dev machine in the error stack. Is that crazy or what, The files are published and being hosted on a server machine and the error is pointing to a line of code on my local dev box. I feel like I am losing the plot. Can someone pls help be clear the air here because this is very weird

Answer 1

The strange thing about the error is
that it points to my local dev
machine in the error stack. Is that
crazy or what
No it is not :-) The pdb (program database file) holds the information about the files.
http://msdn.microsoft.com/en-us/library/ms241903.aspx
Since you compiled it locally before deploying to the server, the PDB stores the information about your local files. It does not mean your server is talking to your development box.

Answer 2

Turn off your development box, and re-run the app. Something's hitting your dev box without you realizing it.

Answer 3

The stack trace references file paths based on the development machine you compiled it on. To remove these artifacts for a production server, you should compile in release mode which will not contain full debug info.
