How can I include line numbers in a stack trace without a pdb?

by

You can’t get a stack trace with line numbers directly from your application unless you bundle the PDB. However, if you have the PDB files for the same version of the app that you ship to your customers, and you don’t mind some light scripting, then you can turn the .NET stack trace and IL offsets back into line numbers.

During your build process, use Mike Stall’s pdb2xml converter, distributed as part of his excellent MDbg managed code debugger, and store them some place secure (e.g., source control). When you get a stack trace back from the client, you can query the IL offset from the XML data to determine the relevant line number. If your stack traces get submitted to a website, you can even automate the conversion, so that developers will already be getting fully detailed stack traces by the time the cases hit their inbox.
