How do you target the same NuGet package, with different versions, within the same .Net MAUI project?

Question

I'm seeing the following NuGet version conflict error after upgrading a Xamarin Forms library project to .Net7.0 MAUI;

"Version conflict detected for Xamarin.Android.Support.Annotations.

Install/reference Xamarin.Android.Support.Annotations 28.0.0.3 directly to project Library_Upgrade to resolve this issue.

Library_Upgrade -> Xamarin.Azure.NotificationHubs.Android 1.1.1 -> Xamarin.Android.Support.v7.AppCompat 28.0.0.3 -> Xamarin.Android.Support.Annotations (= 28.0.0.3)

Library_Upgrade -> Xamarin.Android.Support.Collections 28.0.0.1 -> Xamarin.Android.Support.Annotations (= 28.0.0.1)."

It seems two packages need different versions of Xamarin.Android.Support.Annotations (28.0.0.3 and 28.0.0.1).

If I do what the error suggests and install 28.0.03 directly, it doesn't install the package as the dependency on 28.0.0.1 stops the update.

Answer 1

Have you tried removing:
Xamarin.Azure.NotificationHubs.Android and Xamarin.Android.Support.Collections from your project.

Then try to install:
Xamarin.Android.Support.Annotations version 28.0.0.3

Finally reinstall:
Xamarin.Azure.NotificationHubs.Android and Xamarin.Android.Support.Collections to your project

This should force the installation of the required version of Xamarin.Android.Support.Annotations (28.0.0.3) for both packages, and resolve the version conflict.
