Description

I've tried making an iOS binding library in VS for Mac.
I used Sharpie to create both definitions files, fixed what was wrong in them( NSArray -> T[] ).
The project compiles.
I reference it in MAUI app and MAUI class library with condition:
<ItemGroup Condition="$(TargetFramework.Contains('-ios')) != false "> <ProjectReference Include="..\iOSBinding1\iOSBinding1.csproj" /> </ItemGroup>
I Cannot access any type declared in the binding library, in my app/class library.

The Android Binding Library works fine under Visual Studio for Windows,
Under the reverse condition in the csproj.

Steps to Reproduce

1. Create Binding Library wrapping a .framework with native reference and Sharpie's output in the:
   ApiDefinition.cs
   StructsAndEnums.cs
2. Reference the project in a Maui Class Library/Maui App.
3. Try to use any type declared in the binding library

More info:
That same .framework wrapped in Xamarin.Formsm iOS binding library, works in a Xamarin.Forms project.
I believe with the same Api and Enums output from Sharpie.

@jsuarezruiz Hi
I can't upload propriety .framework to github, in order to create a repro.
I've just created a solution with a basic MAUI class library,
an ios binding library,
and referenced it in the class library using the condition above.
There's nothing much to it other than that.

@orwo1 I believe this to be a duplicate of #10148 - does it work if you build the binding project separately, and then reference the resulting assemby (.dll) from the main project?

Hi @rolfbjarne
Haven't tried that, will check this option and get back to you here.

Hi @rolfbjarne
Your suggestion seems to work, and by referencing the dll I was able
to access types defined in it.
I guess the next question is whether Microsoft knows of this issue?

I'm not sure I understand what issue you're talking about?

The issue of a project reference not working the same way a dll file reference works (or vice versa).
This is not an issue?
