The annotation for nullable reference types should only be used in code within a '#nullable' annotations context.

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

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

Nullability of reference types in return type of 'Task? BackgroundService.ExecuteTask.get' doesn't match implicitly implemented member 'Task IConnection.ExecuteTask.get' (possibly because of nullability attributes).

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

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

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

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.
