[rabbitmq-discuss] Security Exception in IIS using RabbitMQ Client

[Dave Seltzer]

Thanks for your help Tim,

It seems like this isn't an issue with actual file IO, but rather Code
Security.

I've tried setting <trust level="Full" originUrl="" /> in the web.config,
but it doesn't seem to help.

The full stacktrace is below.

[SecurityException: Request for the permission of type

since I looked at IIS, so I can't tell you exactly where to set this up
until I'm in front of a browser, but checking msdn for Code Access,
FileIOPermission, assemblies and IIS is where I'd start if you want to get
a head start. Post the list if you figure it out first please! :)
