Description

Before .Net Core, adding an ETag to the response header was possible using:

config.MessageHandlers.Add(new ETagMessageHandler());

Using .Net Core, how can I achieve the same: add an ETag to the header when an operation is against a single entity?

Essentially I am looking for a way to enable concurrency checking using the .Net Core OData Library.
See link to OData repository for more info.

Research direction

Start with the linked RESTier ETag documentation and compare its ETagMessageHandler approach with the current ASP.NET Core OData library. Identify the supported path for enabling concurrency checking on single-entity operations; the work is complete when that path is implemented or documented and verified for ETag response headers.
