A question I have been asked many times recently is how do you debug a DotNetNuke module that has been developed using the WAP (Web Application Project) development model.  This is a question that I have known the general answer to for quite some time, but I have never actually had a need to truly debug one of my custom modules.  During the course of helping a client with an issue today I actually took the time to document all steps necessary to debug a WAP DotNetNuke Module within Visual Studio 2005.  This article will walk you through all steps necessary to debug your project.
