Did I find a problem or did I not understand correctly? (Validation with Annotations) #126

Hi Community, I am testing CommunityToolkit.mvvm and I have some problems ...

1

I have a property of type string that must contain an EmailAddrtes

This is the property definition: [ObservableProperty] [NotifyDataErrorInfo] [Required] [EmailAddress] public string? _mailAddress;

This is working perfectly

But I also have a string property that should contain a date, but I can't get the correct validation.

This is the definition: [ObservableProperty] [NotifyDataErrorInfo] [Required] [DataType(DataType.DateTime)] // Doesn't work [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)] // Doesn't work
public string? _birthDate2;

I think the problem is in the annotation: [DataType(DataType.DateTime)]

But what do I have to write to get the correct validation?

2

In addition to validation, I would also like to get the required formatting, but that doesn't seem to work either.

A general problem, not specifically of the toolkit. When I search for something on GitHub / NuGet I find dozens of occurrences of packages of similar name... Wouldn't it be appropriate to assign a unique identifier so that the poor programmer knows which one to choose? Thank you for your attention.

Best regards
