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.

Non-nullable field '_client' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the field as nullable.

Cannot convert null literal to non-nullable reference type.

Converting null literal or possible null value to non-nullable type.

Nullability of reference types in type of parameter 'handler' of 'void QuickHandlerFactoryAsync.Release(IHandleRequestsAsync handler, IAmALifetime lifetime)' doesn't match implicitly implemented member 'void IAmAHandlerFactoryAsync.Release(IHandleRequestsAsync? handler, IAmALifetime lifetime)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'value' of 'void MyLargeCommandMessageMapperAsync.Context.set' doesn't match implicitly implemented member 'void IAmAMessageMapperAsync<MyLargeCommand>.Context.set' (possibly because of nullability attributes).
