Description

After upgrading the Plugin.FirebasePushNotifications package from version 3.0.17 to 3.0.28 or to 3.0.21, I encountered the followin build errors when building the project:

If I downgrade the package version back to 3.0.17 then it's working again.
I'm testing on real iOS device via Mac and VSCode.
MAUI version:
maui 9.0.14/9.0.100 SDK 9.0.100

I didn't encounter any issues when using Visual Studio on a real Android device with Windows 10.

Steps to Reproduce

Install or upgrade the package with version 3.0.28 or 3.0.21

Expected Behavior

• Build Done

Actual Behavior

• Build Failed

Basic Information

• Version with issue: 3.0.21, 3.0.28
• Last known good version: 3.0.17

Ok, not cool. Did you clean the bin/obj folders before you run a full solution rebuild?

[Th3L0x]

Yes, multiple times :/

[thomasgalliker]

I just installed 3.0.28 in one of my production apps. I'm using JetBrains Rider 2024.3.3 on Windows 10. The app solutions are all on .NET 8 with MauiVersion 8.0.100. Maybe one of these components makes the difference?

[Th3L0x]

Unfortunately, I don’t know. I’m using .NET 9.0, and all my NuGet packages and workloads are up to date. It was working fine before version 3.0.21. :/
Also, I’m using these two packages:

<PackageReference Include="Plugin.InAppBilling" Version="8.0.5" />
<PackageReference Include="Plugin.MauiMTAdmob" Version="1.7.1" />

Could these be causing any interference?
