a screenshot of the problem in XS 6 preview 3
With the Xamarin Studio 6 (preview 3) on Mac we are getting a ton of warnings that show up as squiggly lines underneath types in the text editor. I found out that it is because of the following situation, which may not be something you guys test for. To reproduce:
1. Create an iOS project.
2. Create an iOS Today Extension project.
3. Create a shared project and reference the shared project from the iOS project and the iOS Today Extension project.
4. Create a couple of classes in the shared project. Reference one of the classes in the shared project from another class in the shared project.
5. Build. Notice that everything is fine.
6. Now create a reference to the iOS Today Extension Project from the iOS project. This is necessary as stated here: "The Container app must have a reference to the Extension." https://developer.xamarin.com/guides/ios/platform_features/introduction_to_extensions/
7. Build again. Notice that now warnings appear for classes in the shared project that reference other classes in the shared project. That's because iOS sees those types twice: once for the iOS project itself, and once for the iOS Today Extension project. Interestingly the warnings do not show in the build output; they only show up in the Xamarin Studio text editor.
See the attached screenshot.
