Background tasks with Native AOT

[Diegorro98]

I'm looking to use Native AOT for my app, but unfortunately, I am having some issues with the background tasks.

I have the same code from the out of process BackgroundTask example at WindowsAppSDK-Samples and it raised the following exception:

System.NotSupportedException: 'Built-in COM has been disabled via a feature switch. See https://aka.ms/dotnet-illink/com for more information.'

I tried some suggestions I found on the web, such adding [GeneratedComClass] to the BackgroundTask class, but it required some changes that copilot suggested me, like creating the following interface:

[GeneratedComInterface]
[Guid("A GUID")]
public partial interface IBackgroundServerTaskCom : IBackgroundTask
{
}

And make BackgroundTask inherit from this class.

Unfortunately, that did not work as I faced the same error.

I there anyway to achieve NativeAOT on out of process backgroundTasks?

@Diegorro98 Did you try adding this?
<BuiltInComInteropSupport>true</BuiltInComInteropSupport>
Per:
