While trying publish the MAUI app with Razor Class library for ios, we get below issue. Kindly help to resolve.

*C:\Program Files\dotnet\sdk\6.0.301\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(267,5)
: error NETSDK1005: Assets file 'C:\Users\Usr\Documents\MauiProj\MobilePoc\RazorClassLibrary\obj\pr
oject.assets.json' doesn't have a target for 'net6.0-ios'. Ensure that restore has run and that you have included 'net6
.0-ios' in the TargetFrameworks for your project. [C:\Users\Usr\Documents\MauiProj\MobilePoc\RazorC
lassLibrary\RazorClassLibrary.csproj]

We tried,

  • Restore the nuget packages
  • Clearing /Caches/Xamarin/XMA/ folder in both windows and mac machines
  • Updating Visual Studio
  • Adding dotnet workload

We have below content in .csproj files
In MyMobileProj.csproj

<PropertyGroup>
