I can't find any documentation on how to publish your app to the app store from Visual Studio? Is this a case of having to use Xamarin Studio once you are ready to submit your app?
It seems a bit odd that xamarin gives you the opportunity to use Visual Studio but then has absolutely no instructions on how to create a bundle to submit your app to the app store..
Any tips on how to do this with Visual Studio would be great.
As far as I know, there's no way of submitting to AppStore (or even TestFlight) from VS.
I believe that you can only submit builds to the App Store using Xcode or Application Loader. Both Mac programs.
Personally I make a release build in Visual Studio, and then click the 'Show IPA File In Build server' button.
If the buttons greyed out, right-click your iOS solution, select properties. Then go to 'iOS IPA Options' and check 'Build ad-hoc/enterprise package (IPA)'
Then I go to my Mac and start up Application Loader and drag the IPA file there.
