'MessageHubPlugin<TPlugin, TState>.DisposeAsync()' hides inherited member 'MessageHubPlugin<TPlugin>.DisposeAsync()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

The member 'MessageHub<TAddress>.Address' does not hide an accessible member. The new keyword is not required.

This async method lacks 'await' operators and will run synchronously. Consider using the 'await' operator to await non-blocking API calls, or 'await Task.Run(...)' to do CPU-bound work on a background thread.

The local function 'DeliveryFilter' is declared but never used
