Error submitting Monotouch application - "Unable to locate the metadata-template.xml file within the application"

I'm trying to submit an iPhone application developed in MonoTouch and I'm getting the cryptic error "Unable to locate the metadata-template.xml file within the application".

I'm us开发者_如何学编程ing the Application Loader and the application runs fine on the simulator and an iPhone.

Any help or pointing me in the right direction would be greatly appreciated. I don't even know where to start looking...

Is this a file that you deleted from your project, but is still referenced somewhere in a config or metadata file?

I received this problem and believe it was cause by my incorrectly saving over an Info.plist file in a framework in my post-build script. After fixing this, I needed to quit Application Loader and resubmit the app for it to go through.
