Xamarin binding project on iOS fails to integrate in the projects of the same solution #16299

Closed mdima closed 1 year ago

mdima commented 2 years ago

Steps to Reproduce

  1. Open the project at https://github.com/mdima/Test.ZoomBinding;
  2. Start compiling the project ZoomSDKSampleApp.iOS and it will fail, because VS doesn't find the objects inside the binding library (MobileRTC_iOS);
  3. Also if you browse the "Class view" of the project ZoomSDKSampleApp.iOS, the referenced library Zoomios is empty.
  4. Anyway, the MobileRTC_iOS project compile successfully. If you remove the project reference to MobileRTC_iOS inside the project ZoomSDKSampleApp.iOS and you add the DLL generated from the binding project (Zoomios.dll), the project ZoomSDKSampleApp.iOS will compile successfully and the Class view will regularly show the classes exposed by the binding project.

Expected Behavior

The expected behavior is that the functions exposed by the project MobileRTC_iOS are usable by the project ZoomSDKSampleApp.iOS using a project reference.

Actual Behavior

Now it is necessary to reference the DLL generated by the project, not the project itself.

Example Project (If Possible)

I created a sample project here: https://github.com/mdima/Test.ZoomBinding

This is because your combining a .NET 6 iOS Project:

% cat ZoomSDKSampleApp/ZoomSDKSampleApp.csproj | head -n1

<Project Sdk="Microsoft.NET.Sdk">

with an legacy binding project:

% cat MobileRTC_iOS/MobileRTC_iOS.csproj | head -n5

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
    <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform>

Try converting your binding project to NET6 and see if the behavior improves.

Hi, well... I was searching the documentation and trying this a lot, but still in a NET6 binding project I am not able to reference a native iOS framework... Does anyone knows any guide about that?

Also: I understand that most of the effort is on NET6 and Maui, but the issue is on Xamarin Forms, at least XF became not supported I should make it run on that environment.

Thanks, Michele

This should work just fine in a .NET binding project:

https://github.com/mdima/Test.ZoomBinding/blob/2b0067bf4286b784caa72e85f7fe4b226c630472/MobileRTC_iOS/MobileRTC_iOS.csproj#L255-L258

Please let us know if this works.

Xamarin.Forms isn't supported in .NET, you'll have to upgrade to MAUI.
