I have tried to compile my .NET 5 bare http server project with Native AOT without reflection. This is possible for a normal http connection, but not for a https connection because in Microsoft.AspNetCore.Hosting.ListenOptionsHttpsExtensions the line of code:

var loggerFactory = listenOptions.KestrelServerOptions?.ApplicationServices.GetRequiredService() ?? NullLoggerFactory.Instance;

that appears twice in this class requires reflection. Could it be changed to:

var loggerFactory = listenOptions.KestrelServerOptions?.ApplicationServices?.GetRequiredService() ?? NullLoggerFactory.Instance;

so that it has the ? after ApplicationServices. In this way I believe the reflection can be avoided.
