I am working on a custom HttpHandler for our Umbraco 8 website. The handler is working in general, but I need to add a piece to it that requires access to Umbraco's MemberService and MediaService, and I'm confused about how this should be done.
I updated my handler to inherit from UmbracoHttpHandler, and this looks like it should give it access to the services via Current.Services. When I try to access those object instances directly inside the ProcessRequest method, though, I get an Object reference not set to an instance of an object. error.
I have also tried injecting the services via LightInject, and it looked like instances were getting injected, but I was still getting a null reference exception on MediaService. I was just specifying the desired dependencies in a constructor, but not registering the code as a component or anything; I wasn't sure if that was needed, or how to do it.
Going to answer my own question here: after reading https://our.umbraco.com/documentation/Reference/Common-Pitfalls/ again, I see that UmbracoHttpHandler is mentioned as one of the base classes that exposes the services, and that the existing instances should be used instead of DI. I am having an issue with that, but I'm going to make a separate thread to avoid confusion.
Proper way to access services from custom HttpHandler?
Hello,
I am working on a custom HttpHandler for our Umbraco 8 website. The handler is working in general, but I need to add a piece to it that requires access to Umbraco's
MemberServiceandMediaService, and I'm confused about how this should be done.I updated my handler to inherit from

Can anyone point me in the right direction?
