How to create powerful validation with FluentValidation in .NET apps

I don't believe you need the condition for the ProductImageValidator - if the collection of ProductImages is empty, nothing will be executed anyway.

Nice Video!!!

Awesome video.

I have an API, the validation message should be returned in several languages. In the Person class there is a property Language, how can I return the error messages in the right language (fr, en, de)?

hello im still a beginner .. i dont understand why i should validate domain model when im going to use FluentValidation to validate the Dtos and if the validate success then im going to map it to domain models using automapper .. so am i wrong that there is no need to validate domain models?

I just notes that in the ProductValidator constructor you set a rule for product price which must be > 0 line 15
and then in the ValidatePrduct method you check for price <= 0 and throwing exception line 20.
Aren't those line equivalent or there is another purpose for that.
Thank you very much.

Excellent and smooth explanation.
Thank you very much.

What the point is using static constructor for Product class instead of regular? The no way to use validation in former?

Thank you for the video .. can you make a video about crud with nested resources wired up to front end ?

It would be intresting to me to see how you get the Rich Domain Objects from a Database eventually using EF. Should I use DTOS ?

Thanks very much for this great videos. I like my validators out of the domain layer, I dont like to make the domain dependant on an external package. But then what is the best way to do it? Maybe that could be another video. Thanks again for the great content

thanks, well explained

Thank you for making more videos

Thanks very much. Love to see more on this topic including how it is wired up to front end as well.

Very powerful video, well explained. My best compliment.
