That's a very useful video, thank you so much

Very good explanation of the Data validation Sean. I think you could make the AddError() and CleanError() a bit shorter by introducing [CallerMemberName] as the default attribute in the methods. This way you can bypass the "nameof(propertyName)" that you use often. so it would be: void CleanErrors([CallerMemberName] string propertyName = null) { ... }.

Nice spinner 😎

Great content as always, how would we handle the Clear Errors if we wanted to implement multiple errors on the same field ? Like a re-usable "RequiredField" method ?

@jametime7491 2 года назад

Is there a way we can share the AbstractValidator(of FluentValidator) with this to share the same validation code on back-end + front-end, by using ValidationRule perhaps?

Sean- The video is great but I can't seem to get the Spinner to show. I have been over the code several times- is the Checkbox control in the dll by chance?

If I leave in the code for throwing an exception while loading, should it still try to load after going back with the cancel button even after deleting that line at 18:51?

Check if StartDate < EndDate would not be a business rule? Wouldn't it be better to address this in the Domain (separation of concerns/DDD)? Would you have any example of MVVM + DDD, implementing the Domain and data access in a Rest API?

Hey Jader, I feel a bit uneasy about this as well. You could certainly extract this logic to the domain layer and encapsulate it into something more pleasant. I would reallyyyy like to do a series on WPF + ASP.NET, where we build a Rest API with ASP.NET. I've thought of an idea for this series. I spend most of my time building APIs nowadays anyways, so I think this would be fun!
