Please include your full build logs, crash reports (if any), test case (to reproduce) and all your version information.

To get full build logs just set the log verbosity to diagnostic at the following locations:

On Visual Studio Windows you also want to add -v -v -v -v to the mtouch additional arguments by right-clicking the project in the solution explorer and selecting Properties. Note: this is done automatically on Visual Studio for Mac when the log verbosity is set to diagnostic.

The easiest way to get exact version information:

We have a Xamarin iOS project. We wanted to support iOS notification extension and hence added iOSNotificationExtension project to the project. Now main project has an reference to iOSNotificationExtension project. We have shared project 'eg: BusinessLogicProject' which includes encryption/decryption and other shared code snippets. Now we want to use the decryption logic written in the BusinessLogicProject in iOSNotificationExtension project as well. Hence I added the reference of BusinessLogicProject in iOSNotificationExtension project. Note that the BusinessLogicProject is already added as the reference to main Xamarin iOS project. Hence we have reference of BusinessLogicProject in both main Xamarin iOS project and iOSNotificationExtension project.

When we build after adding all the references, multiple warnings are being shown in the file. Note that the warnings are not listed in the errors/warnings pad of the IDE. Its all listed in the file itself. Since it is a shared project we were expecting not to get any warnings or errors while referencing them in main project along with extension project.

If there is a class named: public class WaveList : List { } in the shared project. After adding the references I am getting following warning: "The type 'WaveList' in shared project 'projectPath/BusinessLogicProject/GenericTypeClass.cs' conflicts with the imported type 'WaveList' in 'iOSNotificationExtensionProject, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'. Using the type defined in 'projectPath/BusinessLogicProject/GenericTypeClass.cs'."

We are guessing the main project and the iOS notification extension project are maintaining separate instances of the shared library classes.

Kindly let us know if this has been resolved. And guide us to solve the warnings since we do not want to duplicate code in the shared project in extension project because of the warnings.

We came across a similar issue that was reported in the forum. It seems exactly like the following bug report which Xamarin claims to have fixed: https://bugzilla.xamarin.com/show_bug.cgi?id=44746

I can reproduce this in VSfM with the test case from bug #44746:

The warning does not show in up the build log, it's purely a UI issue.

Any update on this issue? I am also facing the same issue in Visual Studio Community 2017 for Mac Version 7.5.2 (build 40) and Xamarin iOS Version: 11.12.0.4.
