I have implmented a custom profile provider class from the abstract ProfileProvider class. What is the proper way to access the DI container. I have tried this

HttpContext.Current.GetScope().ServiceProvider.GetService(typeof(IXyz))

But I am not sure if this is the correct way. I am currently on version 9.13.0

Starting in DNN 10, you can just add your dependency as a constructor parameter and the platform will provide it automatically. Until then, getting the service provider via the HTTP context is a good option, though you may want to make sure HttpContext.Current isn't null (if it is, you'll need to manually construct an instance instead of using the DI container).

My reply seems to have been lost! Thanks for the response - will check that the current context is available. My problem is that the library extension project only has a reference to the abstraction and not the implementation. I could reference the component but that is not an ideal scenario - was going to add to the Component Factory from the startup class but that doesn't work due to the order that the serviceprovider and component on component factory is built. Hmm what to do ...
