Unable to find the ReactiveUI assembly starting from version 19.5.41 in Azure DevOps Pipeline

[Lapinou42]

Hello,

For the past few weeks, I've been experiencing a build problem that only occurs on my Azure DevOps pipeline.

Here are the project characteristics:

• Xamarin iOS / Android (not Forms or MAUI).
• .NET 8.0.204
• Azure Pipeline images: macos-13 or macos-14

The error I encounter is only on Azure; locally on my machine, running the same dotnet build command works fine.
I get this error for all versions greater than or equal to ReactiveUI 19.5.41.

Error CS0246: The type or namespace name 'ReactiveViewController<>' could not be found (are you missing a using directive or an assembly reference?)

This is only happening on iOS, Android works fine.

Do you know what might have changed between version 19.5.39 (working) and version 19.5.41?

Thank you.
