The following exception was thrown in the browser on clicking on the link to edit the details of an existing AGENT (while scheduler was running):

Error did not persist once I closed all browser sessions and restarted the IdB service.

Hi Bob Bradley, are you able to provide any details on reproducing the issue? The only thing I can find that sounds remotely similar is http://stackoverflow.com/questions/3698156/error-cs0006-metadata-file-c-windows-microsoft-net-framework-v2-0-50727-tempo. It says that it can happen from a recompile being triggered whilst under load. Had you recently restarted Identity Broker or updated a .config file?

Adam Bradley - the browser window had been open for a long time (days) but there were no service restarts or config file changes AFAIK. A service restart fixed the problem, so I can only presume it got into a corrupted state due to the nature of changes in the development environment (i.e. not like production where extensibility rarely changes).

Felt this was worth noting for future reference, but no time to spend now on chasing this.

Thanks Bob Bradley.
