* The `EndpointFilterInvocationContext` object provides access to the [`MethodInfo`](/dotnet/api/system.reflection.methodinfo) associated with the endpoint's handler and the `EndpointMetadata` that has been applied on the endpoint.
* The filter is registered using a `delegate` that takes a `EndpointFilterInvocationContext` and returns a `EndpointFilterDelegate`. This factory pattern is useful to register a filter that depends on the signature of the target route handler.
In addition to being passed as delegates, filters can be registered by implementing the `IRouteHandlerFilter` interface. The follow code shows the preceding filter encapsulated in a class which implements `IRouteHandlerFilter`:
