Commented Issue: C:\Users\Stephen\Documents\Repos\Superexpert\AjaxControlToolkit\Server\AjaxControlToolkit\C [27001]

Why is debugger looking here for source code? Is there a work around? How can I point it somewhere else?

Thanks.
Comments: I fixed this on my Solution by adding "CalendarExtender.cs" to the "Do not look for these source files" area under Solution Properties, Common Properties, Debug Source Files. See attached screenshot. I would imagine this to be an easy fix if Stephen can just take a quick look at it...
