Hi, would it be possible for you to provide your binding project and the native library you're bindings as a test case so we can reproduce the issue?

VincentDondain on 20 Jun 2018

Otherwise @rolfbjarne any idea? IIRC you added those new attributes.

VincentDondain on 20 Jun 2018

Here is the entire project which includes the native library.

Xamarin.iOS 11.9.1.24 (f62de47)

Either

Update to a newer version of Xamarin.iOS; or
Rebuild the binding assembly with your current version of Xamarin.iOS

What happens is that you have a binding library (binary) that was compiled with a more recent version of Xamarin.iOS (e.g. 11.10). Your older 11.9 version does not have the new attributes and you get this build failure.

How do I get it to update to 11.10?

Looks like I need to ditch VS2015 for VS2017, would that correct this problem?

comfr3ak on 20 Jun 2018

Please follow these documents to update your Xamarin packages on VS Windows: https://docs.microsoft.com/en-us/xamarin/cross-platform/get-started/installation/windows-preview and https://blog.xamarin.com/staying-date-visual-studio-2017-xamarin-updater/.

Upgraded to VS2017, built the binding project without issue. However, when I added it as a reference to my Xamarin iOS project, there are no methods or classes visible on the binding project dll library. Is this a separate issue I should open or something obvious that I need to check or change? Project attached.

has anyone got this message when compiling a project with reference to the library
