Thank you for your response. I actually just switched to that. I'd rather be able to call it separately, but this will work.

my goal was to get a List<ValidationResult>. but I'm hoping the following will work instead

            var exceptions = new List<Exception>();
            var isIdUnique = await IsCodeUnique(dto.Id, dto.Code);

            if (!isIdUnique)
            {
                exceptions.Add(new UserFriendlyException("Country Code already exists"));
            }

            var isNameUnique = await IsNameUnique(dto.Id, dto.Name);

            if (!isNameUnique)
            {
                exceptions.Add(new UserFriendlyException("Country Name already exists"));
            }

            if (exceptions.Any())
            {
                throw new AggregateException(exceptions);
            }

I don't want to have to duplicate every base crud like create below just to do validation. There's got to be a better way. Please advise.

    public virtual async Task<TGetOutputDto> CreateAsync(TCreateInput input)
    {
        await CheckCreatePolicyAsync();

*** VALIDATE***

        var entity = await MapToEntityAsync(input);

        TryToSetTenantId(entity);

        await Repository.InsertAsync(entity, autoSave: true);

        return await MapToGetOutputDtoAsync(entity);
    }

I find that hard to believe that the only methods you can call our the base CRUD. Certainly you should be able to add a permission and be able to call a custom method in the Application Service.

Without this flexibility, that means having repetitive code many many times. I want to use the base CRUD but validate. This should be very very basic.

I reverted back to my original implementation which does the validation in the application service. However I still need my second question answered because I have the same issue.

when calling the service from the web project I can successfully use Service.UpdateAsync but Service.ValidateAsync needs permissions. How do I configure a proper permission?

• ABP Framework version: 4RC
• UI type: MVC
• Tiered (MVC) or Identity Server Seperated (Angular): no

I really don't like doing this validation in the DTO, but I was unable to get it to work any other way. It would be great if the second half of your validation page (https://docs.abp.io/en/abp/latest/Validation) had more detail and specific usage on an alternative method.

Regardless, I'm dealing with a few issues with this approach:

• there really should be a ValidateAsync(ValidationContext validationContext) method
• when calling the service (IsIdUnique for example) I'm getting
  probably a simple fix, but the only way I found around it is removing authorization from the service which is obviously not a real fix.

Thanks

            var isIdUnique = Task.Run(async () => await service.IsIdUnique(Id))
                                 .Result;

            var isNameUnique = Task.Run(async () => await service.IsNameUnique( Name))
                                   .Result;

            {

                {
                    "Name"
                }));
            }

            return validationResults;
        }
    }

Switching

public class CountryAppService : ApplicationService, ICountryAppService

to

    public class CountryAppService : CrudAppService<Country,CountryDto, string, GetCountriesInput, CountryCreateDto, CountryUpdateDto>, ICountryAppService

resolved the issue

I have a project for you to review this. Please provide an email address .

• **ABP Framework version: 4.0.0-rc.3
• UI type: MVC
• Tiered (MVC) or Identity Server Seperated (Angular): no
• Exception message and stack trace:

I am having all sorts of trouble with this error. Sometimes it works once, sometimes not at all

This is coming from an ABP Suite generated ApplicationService

public class CountryAppService : ApplicationService, ICountryAppService

This is being utilized by a Blazor component hosted in a razor file

<app>
    <component type="typeof(CountryManager)" render-mode="ServerPrerendered" />
</app>

I had no problems whatsoever with v3.

Let me know if you require additional information. Thank you

my only outstanding issue is

thank you
