Trouble simply getting started - #8603

Using ABP Studio (UI); Create a new solution, MVC Single Layer, SQL.

Build and run, errors! Have re-created the solution 3 or 4 times always the same result. MANY errors.

Here are several of the messages:


'BookAppService' does not implement interface member 'IReadOnlyAppService<BookDto, BookDto, Guid, PagedAndSortedResultRequestDto>.GetAsync(Guid)'. 'BookAppService.GetAsync(Guid)' cannot implement 'IReadOnlyAppService<BookDto, BookDto, Guid, PagedAndSortedResultRequestDto>.GetAsync(Guid)' because it does not have the matching return type of 'Task<BookDto>'.

'BookAppService' does not implement interface member 'ICreateAppService<BookDto, CreateUpdateBookDto>.CreateAsync(CreateUpdateBookDto)'

The type or namespace name 'Book' could not be found (are you missing a using directive or an assembly reference?)


The project has all the class objects, for example \Services\Books\IBookAppService.cs and \Services\Dto

Ideas? Quite frustrated by not being able to simply get a project to build. Thanks, Alan

    hi

    Can you update your Studio to 0.9.19 and try again?

    Thanks.

    Maliming, Easy to solve:

    Built a project using 0.9.20, which appears to have a minor bug.

    fix missing references
        in BookAppService
            using Avklare.Do.Entities.Books;
            using Avklare.Do.Services.Dtos.Books;
            
    

    Thank you
