ConnectionAdapters have been removed from Kestrel

ConnectionAdapters have been removed from Kestrel

As part of the move to move pubternal APIs to public, we've removed the concept of an IConnectionAdapter from Kestrel. Connection adapters are being replaced with connection middleware (very similar to http middleware in the ASP.NET Core pipeline but for lower level connections). HTTPS and Connection logging have been moved from connection adapters to connection middleware so those extension methods should continue to work seamlessly (but the guts have been re-implemented). See dotnet/aspnetcore#11412 for more details.

Discuss this issue on dotnet/aspnetcore#11475.
