Possible null reference assignment.

Dereference of a possibly null reference.

Nullability of reference types in type of parameter 'exception' of 'void GenericLogger<T>.Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter)' doesn't match implicitly implemented member 'void ILogger.Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception? exception, Func<TState, Exception?, string> formatter)' (possibly because of nullability attributes).

Nullability in constraints for type parameter 'TState' of method 'GenericLogger<T>.BeginScope<TState>(TState)' doesn't match the constraints for type parameter 'TState' of interface method 'ILogger.BeginScope<TState>(TState)'. Consider using an explicit interface implementation instead.

Possible null reference assignment.

Dereference of a possibly null reference.

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

Possible null reference return.

Possible null reference argument for parameter 'value' in 'void IKeyValueStore.Set(string key, object value)'.
