Can't upload application from Application Loader

I finished work on an iPhone app in MonoDevelop and got a distribution provision from Apple. In the Release|iPhone build of MonoDevelop I set the 'Iphone App Bundle Signing' option开发者_如何学运维 to use the distribution user/provision and I built the app.

It created a .app in the bin/release folder. I tried uploading it using the application uploader but it wouldn't let me select the .app I had just built (it was greyed out)

Any ideas why that might happen?

I believe that the Application Loader only accepts zip files. Have you zipped up your app bundle?

Double Click 'Deliver your app', then you should be able to select the .ipa which is different than a template.

you have to create an .ipa file. take a look a this: MonoTouch Enterprise - Deployment
