While porting a C++ Syncronous extension to Asyncronous for VS2019 and later versions. The class is derived from “IAsyncLoadablePackageInitialize” and “IAsyncServiceProvider” . The interfaces “initialize” and “QueryServiceAsync” have been written , but while loading the package an error is thrown in the “ActivityLog.xml”
Autoload request for package “{}” for UI context “{}” is ignored because package does not support background loading. See https://aka.ms/AA52xzw for more details.

Welcome to Microsoft Q&A forum.
Is there any code in your project still remains synchronize when loading the package in VS? Could you please share us more information like some corresponding code snippets for further check?

2023-05-30T08:01:32.56+00:00 Currently I have commented the IvsPackage::SetSite method , and have a messagebox to be displayed in the IAsyncLoadablePackageInitialize::Initialize and IAsyncServiceProvider::QueryServiceAsync . Still I get the same error for background loading .
