问题
I'm trying to register a subscriber to events for using the following example. When I use the POST method, I get a bad request error (400), so I've attempted to visit the url where the request is sent and received using a browser and received the following stack trace:
When visiting
https://localhost:44300/api/webhooks/registrations
I get:

Based on the source code here, my understanding is that the line below is problematic
string id = await _user.GetUserIdAsync(User);
One of my guesses is that Microsoft's Webhook library requires Identity to be installed (the application where I'm testing this uses SimpleMembership).
Is this the problem? Can this be resolved easily?
