Argument of type 'Money' cannot be used as an output of type 'Dto.Money' for parameter 'Amount' in 'void PaymentRequested.Deconstruct(out Guid PaymentId, out Guid OrderId, out Money Amount, out Address BillingAddress, out string Status, out long Version)' due to differences in the nullability of reference types.

Argument of type 'Address' cannot be used as an output of type 'Dto.Address' for parameter 'BillingAddress' in 'void PaymentRequested.Deconstruct(out Guid PaymentId, out Guid OrderId, out Money Amount, out Address BillingAddress, out string Status, out long Version)' due to differences in the nullability of reference types.

Argument of type 'PaymentStatus' cannot be used as an output of type 'string' for parameter 'Status' in 'void PaymentRequested.Deconstruct(out Guid PaymentId, out Guid OrderId, out Money Amount, out Address BillingAddress, out string Status, out long Version)' due to differences in the nullability of reference types.

Nullability of reference types in return type of 'Task<IPaymentResult>? PaymentService.HandleAsync(Func<IPaymentService, PaymentMethod, CancellationToken, Task<IPaymentResult?>> behaviorProcessor, PaymentMethod method, CancellationToken cancellationToken)' doesn't match implicitly implemented member 'Task<IPaymentResult> IPaymentService.HandleAsync(Func<IPaymentService, PaymentMethod, CancellationToken, Task<IPaymentResult>> behaviorProcessor, PaymentMethod method, CancellationToken cancellationToken)' (possibly because of nullability attributes).

Nullability of reference types in return type of 'Task<IPaymentResult?> PaymentService.AuthorizeAsync(PaymentMethod method, CancellationToken cancellationToken)' doesn't match implicitly implemented member 'Task<IPaymentResult> IPaymentService.AuthorizeAsync(PaymentMethod method, CancellationToken cancellationToken)'.

Non-nullable property 'ActionResult' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.

Argument of type 'Func<IPaymentService, PaymentMethod, CancellationToken, Task<IPaymentResult?>>' cannot be used for parameter 'behaviorProcessor' of type 'Func<IPaymentService, PaymentMethod, CancellationToken, Task<IPaymentResult>>' in 'Task<IPaymentResult> IPaymentService.HandleAsync(Func<IPaymentService, PaymentMethod, CancellationToken, Task<IPaymentResult>> behaviorProcessor, PaymentMethod method, CancellationToken cancellationToken)' due to differences in the nullability of reference types.

Non-nullable field '_next' must contain a non-null value when exiting constructor. Consider declaring the field as nullable.

Non-nullable property 'Message' must contain a non-null value when exiting constructor. Consider declaring the property as nullable.
