Hello,

Thank you for posting in our community.

I have created and attached a sample project demonstrating how to integrate igniteui-angular-wrappers in an Angular project with ASP.NET Core. The steps I took were the following:

1. Run dotnet new angular -o my-new-app
2. Navigate to ClientApp folder of the project
3. Run ng update --force @angular/cli@10
4. Remove the following line in the main.ts file because of this issue: export { renderModule, renderModuleFactory } from '@angular/platform-server';
5. Run ng add igniteui-angular
6. Run npm i igniteui-angular-wrappers@10.0.0
7. Change the start command in the package.json file because of this issue to: "start": "echo Starting... && ng serve"
8. Add Ignite UI for jQuery dependencies in the index.html file
9. Import IgniteUIModule from igniteui-angular-wrappers package in the app.module.ts file

The steps listed above should allow you to successfully run a project.

Please let me know if you need any further assistance with this matter.

After further investigation, in order to load the data asynchronously, the igTree component has to be loaded using the ComponentFactoryResolver in the subscription of the observable.

I have modified and attached the previous sample for your reference. Please test it on your side and let me know whether it helps you achieve your requirement.
