Configuring Application Debugging

The web.config file includes a

<compilation ...> section that sets whether debug

mode is set for an ASP.NET application. A typical compilation section follows:

<compilation

defaultLanguage="vb"

debug="true"

/>

Setting debug="true" (which is case-sensitive) enables debug mode for your application.

This means the .PDB file for your assembly will be copied to the application's /bin

folder, which means detailed debug information (stack trace, line numbers, and so on)

will be provided in response to exceptions. Note that there is a significant performance

penalty to application running in debug mode. Individual pages can also be set up to run

in debug mode by setting debug="true" in the individual page directive.
