Answer 1

According to this github post, https://github.com/dotnet/aspnetcore/issues/18193 , RequestCookieCollection() was deliberately made internal so you have to use the interface IRequestCookieCollection.

If you notice, Visual studio auto suggests using the interface in both situations.

You can either use the interface or copy the implementation code and use it directly but that leaves you with possibility of a change being introduced that makes the copied code out of date.
