hey thanks for the question
In short it shouldn't matter - easyauth as a component is injected into the App service request processing pipeline by the platform and managed by the platform - to quote: "It’s built directly into the platform and doesn’t require any particular language, SDK, security expertise, or even any code to utilize." REF https://learn.microsoft.com/en-us/azure/app-service/overview-authentication-authorization
It doesn't matter if you're using net FX , dot net core or something else
