Adding this response to the old thread in case someone like me is tracking down this mystery in an older ASP.Net application. I had one Webform code-behind which did not respond to breakpoints with the "...no executable code..." debugger warning. It was doing my head in as all of the other pages were working fine. I'd done the clean, rebuild, purged the temporary ASP.Net files, no joy.

The culprit with this file was the inclusion of several #ExternalSource directives surrounding some of the member variable declarations. Once those were removed and the project rebuilt, the break point behavior was restored. Those ExternalSource lines were appearing in the generated section of the code-behind. Not sure why they were there.
